Preface

This kitCON-541 Users Manual describes the boards design andfunctions. Precise specifications for the C540U/C541U microcon-

trollers can be found in the enclosed microcontroller Data-

Sheet/Users Manual. If software is included please also refer to

additional documentation for this software.

In this hardware manual and in the attached schematics, low active

signals are denoted by a "/" in front of the signal name (i.e.: /RD). A

"0" indicates a logic-zero or low-level signal, while a "1" represents a

logic-one or high-level signal.

Declaration regarding EMV-Conformity of the

PHYTEC kitCON-541

PHYTEC kitCON Single Board Computers (henceforth products)

are designed for installation in electrical appliances or as dedicated

Evaluation Boards (i.e.: for use as a test and prototype platform for

hardware/software development) in laboratory environments.

PHYTEC products must be operated within protective, grounded

circuitry. Moreover, PHYTEC products should not be operated

without protection circuitry if connections to the products pin header

rows are longer than 3 m.

Implementation of PHYTEC products into target devices, as well as

user modifications and extensions of PHYTEC products, is subject to

renewed establishment of conformity to, and certification of, EMV-Statutes. Only after doing so the devices are allowed to be put into

circulation.

PHYTEC products fulfill the norms of the EMVG-statute only in

accordance to the descriptions and rules of usage indicated in this

hardware manual (particularly in respect to the pin header row

connectors, power connector and serial interface to a host-PC).It is necessary that only appropriately trained personnel (such as

electricians) handle and/or operate these products. PHYTEC products

lacking protective enclosures are furthermore subject to damage by

ESD and, hence, may only be unpacked, handled, operated in

environments in which sufficient precautionary measures have been

taken in respect to ESD-dangers.

The kitCON-541 is one of a series of PHYTEC kitCONs which can

be fitted with different controllers and, hence, offers various functionsand configurations. PHYTEC supports all common Infineons 8- and

16-bit controllers in two ways:

(1) as the basis for Starter Kits in which user-designed hardware

can be implemented on a wrap-field around the controller and

(2) as universal, insert-ready, fully functional micro- and mini-

MODULS which can be embedded directly into the user's

peripheral hardware design.

PHYTEC's microcontroller modules allow engineers to shorten devel-

opment horizons, reduce design costs and speed project concepts from

design to market. Please contact PHYTEC for additional information:

1 Introduction to the kitCON-541The kitCON-541 is a EURO-sized (100 x 160 mm) Evaluation Board.It can be fitted with the single-chip microcontrollers C540U/C541U

in a P-LCC-44 package. The C540U/C541U are members of the

INFINEON C500 family of 8-bit microcontrollers. They are fully

compatible to the standard 80C51 architecture. The C540U/C541U

especially provide an on-chip USB module compliant to the USB

specification. Hence it is possible to connect the kitCON-541 directly

to the USB bus.

Precise specifications for the controllers characteristics can be foundin the enclosed microcontroller manual. The kitCON-541 hardware

manual describes no special features of the C540U/C541U

controllers, as they are not relevant to the basic functioning of this

module.

The kitCON-541 is pre-configured and equipped with all necessary

connectors required for immediate start-up (refer to Figure 2).

2 Quickstart InstructionsIn this chapter you will find a step by step description for putting thekitCON-541 into operation. Please note that the following instructions

refer to the current versions of the FlashTools and the monitor-

program from Keil Elektronik GmbH as of the pressing of this

manual.

To ensure putting the kitCON-541 quick and safe into operation, the

use of the PC-software is described only for DOS. Using it in

conjunction with other operating systems or environments might

cause disturbances of the proceeding, especially of the serial commu-nication.

The kitCON-541 is delivered with a pre-programmed Flash-memory

device. It contains routines for programming the Flash (the so called

FlashTools1) as well as a monitor program2 for easy debugging of

your application. This chapter contains a step by step description for

the use of the FlashTools as well as for using the monitor program.

Here the monitor program from Keil Elektronik GmbH is used as an

example. Monitor programs from other vendors are also available foruse with the kitCON-541.

No Hardware-Handshake-Line is required to invoke communication

between the kitCON-541 and the Host-PC, as the firmware contains a

transmission protocol to ensure fault-free data transmission between

the PC and the kitCON-541.

Ensure that the red Boot-Jumper JP11 - which is located betweenthe USB interface P3 and the power connector X1 - is open.

The monitor program is not protected and can be erased or

overwritten with the FlashTools at any time. Therefore always ensure

that the red jumper JP11 is open, as long as you want to use the

monitor program

Attach a power supply to the power-connector X1. An unregulated8V= to 12V=/500mA power source can be used to supply the

board. Double check the correct polarity of the plug as shown in

Figure 3. Use only a fixed voltage power supply and no power

supply with variable voltage. If the power supply is attached

correctly the red LED 1 will shine.

Push switch S1 to perform a reset. After releasing the reset button

S1 the monitor program on the kitCON-541 will be started.

Invoke the Terminal program MON51.EXE on your Host-PC byentering the following:

mon51 BR19200 [COM port number]

Other communication or terminal programs are not suitable for data

transmission to and from the monitor program on the kitCON-541, as

a special transmission protocol is required. Ensure that only DOS isactive at the time of the invocation.

After a successful start of MON51.EXE the program will appearwith MONITOR-Mode and a # as prompt.

2.2 Starting the kitCON and programming the FlashAt the time of delivery the Flash device is pre-programmed with a

monitor program1. This program is not protected, unlike theFlashTools, and will be overwritten when the following steps are

carried out.

Use of the Flash requires a kitCON-541 with a pre-programmedFlash device mounted on U7 and an IBM-PC or a compatible

system, as well as an unregulated power supply for 8V= - 12V=

/500mA. Typically all jumpers for configuring the kitCON-541

have been set correctly upon delivery of the module.

Connect your Host-PC (COM1 or COM2) to the DB9-socket P1on the kitCON-541 using a serial cable as shown below.

PC DB9-plug COM1,2 kitCON-541 DB9-socket P1

RxD PIN 2 to TxD PIN 2

TxD PIN 3 to RxD PIN 3

GND PIN 5 to GND PIN 5

No Hardware-Handshake-Line is required to invokecommunication between the kitCON-541 and the Host-PC, as the

firmware contains a transmission protocol to ensure fault-free data

transmission between the PC and the kitCON-541.

Ensure that the red Boot-Jumper JP11 - which is located betweenthe USB interface P3 and the power connector X1 - is closed.

Attach a power supply to the power-connector X1. An unregulated

8V= to 12V=/500mA power source can be used to supply theboard. Double check the correct polarity of the plug as shown in

Figure 3. Use only a fixed voltage power supply and no power

supply with variable voltage. If the power supply is attached

3 Pin-LayoutPlease note that all module connections are not to exceed their ex-pressed maximum voltage or current. Maximum input values are indi-

cated in the corresponding controller manuals. As damage from

improper connections varies according to use and application, it is the

users responsibility to take appropriate safety measures to ensure that

the module connections are protected from overloading through

connected peripherals.

As shown in Figure 6, all relevant controller signals are brought out

to the pin-rows ( X3 ) in the middle of the board. Some of the signalsare also available at the VG-96 connector VG1. The kitCON-541 is

also prepared to accommodate an ICE/connect-51 at X2. This special

connector enables easy emulation of the processor. The following

section provides an overview of the pin assignment of the pin-rows

(kitCON-Connector), while the ICE/connect-51 is described in

section 3.2. Sections 3.3 and 3.4 describe the pinout of the DB9-

connector P1 and the USB-socket P3, whereas the VG-96 connector is

descibed in section 3.6.

3.2 The ICE/connect-51The ICE/connect-51 provides an easy possibility for connecting a

standard emulator, which uses the controller on-board, to thekitCON-541. It can be mounted at position X2 (refer to Figure 6). It

carries all data- and address signals. The control signals coming from

the controller are extended via pre-connections at the ICE/connect-51

to the peripheral devices. When using an emulator the control signals

are generated by the emulator. Therefore in this case the pre-

connections must be opened.

Memory Model


29

5 Memory ModelThe kitCON-541 allows flexible address decoding which can beadjusted by software to different memory models. A hardware reset

activates a default memory configuration that is suitable for a variety

of applications. However, this memory model can be changed or ad-

justed at the beginning of a particular application.

Configuration of the memory is done within the address decoder by

means of decoder internal registers: one control register, one address

register and one mask register. All named registers are carried out as

Write-Only-Registers with access to the XDATA-memory of thecontroller. There are two distinct address areas - selectable by means

of the bit IO-SW in control register 1 - by which the registers can be

accessed (refer to the description of the bit IO-SW below). Due to a

lack of read-access, a copy of all register contents should be main-

tained within the application. Reserved bits may not be changed dur-

ing the writing of the register; the contents must remain 0. A hard-

ware-reset erases all registers, while preserving the configuration of

the default memory model.

In the event that you use a pre-programmed Flash containing the

FlashTools - a firmware allowing convenient on-board Flash-

programming - it should be noted that the address FA16 will be pre-

set at the start of your application software (refer to the section

"Control Register 1" below). This is to be noted upon installation of

the software copy of the register contents. Please refer to chapter 12

"FlashTools" for an elaboration.

kitCON-541


The following figure displays the default memory model:

Figure 13: Default-Memory Model after Hardware-Reset

It should be noted that each memory device on U2 and U11 is mapped

into a separate 32KB memory area within the XDATA memory. If no

device is installed on either U2 or U11, memory-access to the

corresponding memory area is not possible. The corresponding

current I/O area is concentrated in an XDATA-address area in which

there is no access to any existing RAM.

In the following sections the registers of the address decoder for con-

figuration of the memory are explained.

EN = 1). This configuration is used within the

FlashTools2for Flash-programming. On account of the

existing restrictions it is either of no or of restricted

use in your application.

In this model 32KB Flash memory located within the

address range 0000H - 7FFFH is accessible, as well as

32KB RAM within the range 8000H - FFFFH. The

Flash memory can only be written in the XDATA-area

and can only be read from the CODE-area. The RAM

can be read as well as written in the XDATA-area.Reading the RAM in the CODE-area is also possible.

The address line A15 of the Flash is derived from the

Control Register 1 (Bit 0, FA15) only in the

programming-model. In the runtime-model (PRG-EN

= 0), the address line A15 of the controller is attached

directly to the Flash device. The bits IO-SW and

RAM-SW are also relevant in the programming-model.

Whereas the bit VN-EN is not relevant.

1: In the event that you use the FlashTools - a firmware allowing convenient on-board Flash-

programming - it should be noted that the address FA16 will be preset at the start of your

application software. This is to be noted upon installation of the software copy of the register

contents.2: A firmware allowing convenient on-board Flash-programming. At purchase of the module

IO-SW: By means of this bit the I/O-area of the module can be

mapped either to the upper or to the lower 32KB of the

address space. After a Hardware-Reset (IO-SW = 0)

the I/O-area is located in the address area from FC00H

to FFFFH. Following setting of the IO-SW-bit, the

I/O-area is located in the address area from 7C00H to

7FFFH.

This I/O-area generally consists of 4 blocks of 256

bytes. In three of these blocks the address decoder

provides a pre-coded Chip-Select-Signal which simpli-

fies the connection of peripheral hardware to the

module.

8/7/2019 KC-541

37/64

Memory Model


33

These Chip-Select-Signals are activated by XDATA-

access (Read-Write access) to the corresponding

address area. The fourth block is reserved for

accessing the register internal to the decoder (Write-Only access). Hence, this block is not available for

connection of peripheral hardware to the module.

The following diagram illustrates the partitioning of

the I/O-area:

Given this partition, /CS2 and /CS3 function as the

available free Chip-Select signals. The signal /CS-

REG is solely a signal internal to the decoder, which is

necessary in order to access the internal register. /CS1is used to control the external UART. These latter

signals are not available. Connection of peripheral

devices to the area of /CS-REG and /CS1 should not

take place under any circumstances, in order to main-

tain the correct function of the UART and the

FlashTools1 for programming of the Flash.

The internal register is to occupy only the address

ranges 7C00H - 7C03H and/or FC00H - FC03H. Therest of the /CS-REG block remains unused and is

reserved for future expansion.

RAM-SW: By means of this bit the 32KB memory areas of U2

and U11 can be swapped. After hardware-reset (RAM-

SW = 0) RAM U2 is mapped to the memory area from

0000H to 7FFFH whereas RAM U11 can be accessed

in the memory area from 8000H to FFFFH. After

setting of the RAM-SW bit the memory areas areswapped, meaning that RAM U2 occupies memory

from 8000H-FFFFH and RAM U11 is mapped from

0000H-7FFFH. Within the current I/O-area there is no

access to any existing RAM.

VN-EN: This bit enables free selection of von-Neumann

memory1 within the address space of the controller.

After Reset a Harvard2-Architecture is available as the

default configuration. Von-Neumann memory isespecially useful when code is to be downloaded and

subsequently run during running time, as is the case

with a monitor program. The location of the optional

von-Neumann memory is defined through the address-

and mask registers (see below).

Following a Hardware-Reset (VN-EN = 0) the settings

in the address- and mask registers are not released,

which means that no von-Neumann memory isavailable. After setting the bit (VN-EN = 1), the set-

tings in the address- and mask registers are valid and

incorporated in access addressing. This bit is only

relevant in the runtime-model (PRG-EN = 0), other-

wise it is unimportant and ignored.

FA[18..15]: The module can be equipped with an optional 512KB

Flash memory. As the controllers address space is

limited to 64KB, the remainder of the Flash memorycan only be accessed by means of bank memory

switching.

In the runtime-model (PRG-EN = 0), 64KB banks can

be switched by controlling the high address lines

A[18..16] for the Flash through software. For this pur-

pose, register bits FA[18..16] of the address decoder

provide a Latch to which the desired higher addresses

can be written.

1: Memory area in which no difference is made between CODE- and XDATA-access,which

means that both accesses use the same physical memory device, usually a RAM.2: Memory area in which CODE and XDATA-accesses use physical different memory devices,

usually CODE-access uses a ROM or Flash device, whereas XDATA-access uses a RAM.

8/7/2019 KC-541

40/64

kitCON-541


Of particular note is the bit FA15, which is solely

relevant in the programming-model (PRG-EN = 1). As

in this model only 32KB of Flash can be accessed, it

serves as address line A15 for the Flash memory. Inthe runtime-model (PRG-EN = 0) with a 64KB Flash

memory area, to contrast, the address line A15 of the

controller is attached directly to the Flash.

The function of the bits FA[18..16] is dependent on the

hardware configuration of the module and functions as

described above only in connection with Flash devices

of at least 512KB.

5.2 Address RegisterThe address register 7C02H / FC02H functions in conjunction with

the mask register (see below) to define the von-Neumann1- and Har-vard2-memory in the controllers addressing area. By setting the bit

VN-EN in control register 1, the values of the address and the mask

register become valid for the definition of the von-Neumann and the

Harvard addressing space and incorporated in access addressing (refer

to Control Register 1).

The location of one or more Harvard areas can be configured with

both registers. The remaining sections of the addressing area is con-

figured as von-Neumann area in which RAM is accessible throughXDATA as well as through CODE.

The mechanism through which the areas are differentiated is based on

a comparison of the current address with a pre-defined address pattern

of variable width. If a correspondence of the relevant bit positions of

the address is recognised, access occurs according to the Harvard-

architecture. In the case of nonconformity, access occurs according to

the von-Neumann architecture.

Address Register (Address 7C02H / FC02H)

Bit 7 Bit 0

HA15 HA14 HA13 HA12 HA11 HA10 Res.3 Res.

The address register holds the address pattern described above. Each

bit of the pattern is compared with the corresponding address line of

the controller (HA15 with A15, ..., HA10 with A10). On the basis of

the available addresses A15..A10, this produces a granularity of the

configuration of the Harvard-fields of at least 1KB. Areas smallerthan 1KB can not be adjusted.

1: Memory area in which no difference is made between CODE- and XDATA-access,which

means that both accesses use the same physical memory device, usually a RAM.2: Memory area in which CODE and XDATA-accesses use physical different memory devices,

5.3 Mask RegisterThe mask register (addresses 7C03H / FC03H) serves the masking of

single bits in the address register (see above). Following a hardware-reset, all bits within the address register are relevant. By setting the

individual bits in the mask register, all corresponding bits in the

address register will no longer be subject to an address comparison.

Flash-Memory

6 Flash-MemoryThe kitCON-541 is equipped with 5-V programmable Flash devices.Consequently, no special programming voltage is required. The Flash

device already houses a software tool which enables on-board repro-

gramming of, and downloading into, the Flash memory (refer to

chapter12 "FlashTools").

Should this software be erased from the Flash device without having

an equal replacement, reprogramming of the Flash is no longer

possible !

However the software protects itself against any intentional or acci-

dental erasure or copy-over. As the integrated hardware protection

mechanism of the Flash is not used, protection is limited at the soft-

ware level. In the event that you might wish to download your own

programming algorithms or tools into Flash, please ensure that a pro-

gramming tool remains in the Flash memory.

Use of a Flash device as the only code memory results in no or only a

limited usability of the Flash memory as non-volatile memory fordata. This is due to the internal structure of the Flash device, as during

the Flash-internal programming process the reading of data from

Flash is not possible. Hence, for Flash programming, program

execution must be transferred out of Flash (such as into von-Neumann

RAM). This usually equals the interruption of a "normal" program

execution.

As of the printing of this manual, Flash devices generally have a life

expectancy of at least 100,000 Erase-/Program-cycles.

7 The Battery BufferTo prevent loss of data in case of sudden power failure thekitCON-541 can be equipped with a battery. This battery buffers the

memory devices on U2 and U11. However, this battery-buffer is not

otherwise essential to the functioning of the kitCON-541.

Position BT1 (refer to Figure 6) on the component side of the module

is provided for mounting a battery type CR2032. As of the pressing of

this manual, a lithium battery is recommended as it offers relatively

high capacity at low self-discharge. In the event of a power failure at

VCC, the RAM memory blocks will be buffered by a connectedbattery via VBAT.

The current consumption depends on the components used and mem-

ory size. For the standard memory devices used on the board the draw

is typically 1A per device ( max. 100A).

Regarding data and code integrity, please be advised that despite the

battery buffer, changes in the data content within the RAM can occur

given disturbances. The battery buffer does not completely removethe danger of data destruction.

Serial Interface

8 The Serial InterfaceAs the USB interface on C540U / C541U controllers takes the placeof the serial interface, the serial interface is implemented with an

external UART 16C550.

The programming of the external UART is done by means of control-

registers, which can be accessed within the XDATA-memory area at

the addresses from FD00h to FDFFh (or from 7D00h to 7DFFh if bit

IO-SW is set). Eleven registers are located in this address area to

operate the UART (refer to Table 5). This has to be taken into consi-

deration when using standard output functions like printf().

DLAB1 Base address + Register

0 0x00 Receive buffer (read), transmitter holding

register (write

0 0x01 Interrupt enable register

X 0x02 Interrupt identification register (read only)

X 0x02 FIFO control register ( write only)

The exact meaning of the registers and how to program the controller

can be read in the corresponding controller manual of the 16C550A

from Texas Instruments. The source of the functions getkey(),

putchar() und serinit(), included in the software delivered with thekitCON-541, serve - in addition to this information - as examples as

how to use the external UART.

Please notice that due to the use of an etxernal UART neither the

FlashTools nor the monitor program run with variable baudrates. The

baudrate for both is fix at 19200 Baud.

The USB Interface


45

9 The USB InterfaceUSB is a peripheral bus standard developed by PC and telecomindustry leaders. It implements real plug and play for all kind of

computer peripherals, eliminating the need to install cards into

dedicated computer slots and reconfigure the system. Devices

equipped with USB will be automatically configured as soon as they

are physically attached. USB also allows multiple devices -- up to 127

-- to run on the bus.

C540U / C541U controllers are equipped with an on-chip USB mo-

dule, which enables the kitCON-541 to be attached directly to an USBbus. The kitCON-541 runs either as full speed (12Mbit/s) or as low

speed device (1,5Mbit/s). Controlling the USB modul is done by

means of special function registers (refer to the C540U / C541U

Users Manual), whereas the interface is configured with the help of

jumpers on the kitCON-541 (refer to chapter4).

The kitCON-541 can be attached to the USB-bus via USB-socket P3.

The pinout is shown the the figure below.

Hints for Handling the Modul


49

11 Hints for Handling the ModuleThe microcontroller, the external UART and the Flash memory on thekitCON-541 are fitted on PLCC sockets. When changing one of these

components please ensure that appropriate PLCC tools are used and

that the socket and all components remain free from intrusive damage.

It is also adviseable to ensure that the component to be used is pin-

compatible.

Removal of the standard quartz or oscillator is not advisable given the

compact nature of the module. Should this nonetheless be necessary,

please ensure that the board as well as surrounding components andsockets remain undamaged. While unsweating. overheating the board

can cause the solder pads to loosen, rendering the module inoperable.

Carefully heat neighbouring connections in pairs. After a few

alternations, components can be removed with the solder-iron tip.

Alternatively, a hot air gun can be used to heat and loosen the bonds.

FlashTools


51

12 FlashToolsFlash is a highly functional means of storing non-volatile data. One ofits advantages among many others is its on-board programming

capability. Programming tools for the Flash device are included with

the kitCON-541 in the form of a pre-programmed Flash and support

software. These tools allow the download of your application into the

RAM during development. Alternatively, the Flash can be pro-

grammed following development.

The FlashTools incorporate a safety mechanism which ensures that

they can not be copied-over during programming of the Flash device.

Flash devices with two memory sizes are currently available: the

29F010 with two banks of 64KB each or a 29F040 with 8 banks of

64KB each. The first bank (bank 0) houses the FlashTools. Hence the

total memory available is 64KB or 448KB.

The following description is valid only for the use of the enclosed

FlashTools and is not intended as guidelines for use with any other

Flash utility program.

After resetting the module the FlashTools firmware is started auto-

matically. It either enters the programming mode or it starts your ap-

plication. The FlashTools will always occupy the first 64KB bank

(bank 0, FA[18..15] = 0000b) of the Flash memory upon initialisation.

The remaining banks are available to house your application.

Your application will always start in the second 64KB bank (bank 1,

FA[18..15] = 0010b). This is to be noted when preparing a software

copy of the address decoders register contents. Starting at this second

bank enables configuration of the memory according to your needs as

well as addressing additional Flash banks per Bank Switching. The

Tool diskette contains sample programs and hexfiles which illustrate

Bank Switching to other Flash banks.

8/7/2019 KC-541

56/64

kitCON-541


Do not use Flash bank 0 in your application program in order to pre-

serve the FlashTools, which are required for subsequent

reprogramming of the Flash device.

In addition to programming the Flash device, there also exists the

possibility of downloading your application into RAM for testing pur-

poses, such as during the development phase. This means that a hex-

file can be copied to and executed in RAM. Please take into

consideration that your program will remain only as long as the board

is connected to a power supply. If Flash bank 1 contains a suitable

program, which sets up a von-Neumann memory model (which is a

precondition for executing CODE out of RAM) after reset and

performs a jump to a valid start address within the RAM, yourprogram will be executed out of RAM.

This procedure spares the need to engage in multiple

erase/programming-cycles of the Flash memory device when develop-

ing your application. Sample programs and hexfiles contained on the

Tool diskette illustrate how to install the correct memory model, in-

cluding how to start a program out of the RAM.

12.1 Starting the FlashToolsIn order to set the kitCON-541 into its programming mode, the data

line D0 must be pulled through a Pull-Up-resistor of max. 10 k to a

high-level1. A resistor of 4.7 k is recommended, but it should be

noted that this value is only an approximate value, as the resistor to be

used can vary dependent on the external wiring of the data bus. The

resistor is already on the board and can be activated through the red

Bootjumper JP11.

1: configurations with other switches to enter programming mode are available on demand

Connect the module to the serial port of a PC (COM1 or COM2) as

shown below.

PC DB9-plug COM1,2 kitCON-541 DB9-socket P1RxD PIN 2 to TxD PIN 2

TxD PIN 3 to RxD PIN 3

GND PIN 5 to GND PIN 5

Next connect the pull-up resistor to dataline D0 by closing the red

jumper JP11. Then connect the power supply and reset the module.

Start the program FLASHT.EXE, which is part of the FlashTool

software, on the PC. FLASHT.EXE should only be invoked at this

time by entering the following line:

flasht BR19200 [COM port number]

The FlashTools always utilise a baudrate of 19.200 Baud.

FLASHT.EXE can always be exited, except during downloading of

user code, with the special-function key F1.

Note that correct execution of the FlashTools is only possible if the

FlashTools on the module are started first by power-up or reset, and

the terminal-program FLASHT.EXE is invoked on the PC afterwards.

Resetting of the module while the red jumper JP11 is closed is only

allowed after leaving FLASHT.EXE.

After having successfully started the FlashTools you will see the start

menu (s. Figure 18). Here you can select either Flash or RAM-

download.

12.2 Downloading into the FlashSelecting the first option in the start menu will lead to the Flash pro-

gramming menu. The tools enable the partial or total erasure of theFlash device, as well as programming of the device. They also allow

device status information to be read from the Flash. All menu options

are intuitive and always refer only to the selected Flash bank.

Using a Flash memory device of type 29F040 up to 7 banks of 64KB

are available for your applications. A menu option allows specific

memory banks to be selected for programming and erasing. The menu

option is not applicable if the Flash type 29F010 is used. In this case,

bank 1 is the default selection for program storage. Only Intel hexfilescan be used for programming purposes.

After programming of the Flash, disable the pull-up resistor at D0 by

opening the red Bootjumper JP11 and start your program by

performing a normal reset.

The FlashTools include a mechanism which ensures that they are not

erased or copied-over during programming. This preserves the pos-

sibility of future reprogramming.

kitCON-541


12.3 Downloading to RAMDuring development, the RAM-download mechanism can be utilised

to avoid unnecessary erase/programming cycles of the Flash. Choos-ing the second option in the Start Menu enables downloading to

RAM, as well as specification of the start address of the downloaded

program in order to allow subsequent easy execution of the program.

The software provided on the FlashTool diskette uses this start

address to start your program out of the RAM. For that purpose the

address is written to a specific memory area within the RAM.

The FlashTools automatically try to locate this start address during

the RAM-download. Hence, following RAM-download, the lowesthexfile address is assumed to be the start address. If necessary, this

start address can be manually changed.

All menu options are intuitive. The RAM-download allows testing of

an application before it is programmed into the Flash memory.

Be advised that the kitCON-541 executes the program from Flash

bank 1 after a reset. In order to start your application from the RAM

the FlashTool diskette contains the program RUN_RAM.HEX. Thisutility-program has to be programmed into Flash bank 1 before

downloading your application to the RAM. RUN_RAM.HEX sets up

the von-Neumann memory and starts your application through per-

forming a jump to the user-specified start address in the RAM. This

procedure allows the start of your application through a normal reset.
