IODEFINE.h

RX Utilizes “IODEFINE” style peripheral access files

This should be familiar to H8 and SH users

ANSI C compatible method using typedef’d structures

Facilitates generic peripheral drivers

#define SYSTEM (*(volatile struct st_system __evenaccess *)0x80000)

#define BSC (*(volatile struct st_bsc __evenaccess *)0x81300)

#define SCI0 (*(volatile struct st_sci __evenaccess *)0x88240)




#define DMAC (*(volatile struct st_dmac __evenaccess *)0x82200)

#define DTC (*(volatile struct st_dtc __evenaccess *)0x82400)

(struct st_sci *)pSCI = &SCI0

…pSCI->BRR = 720-1; /* set baudrate to 720 clocks */


Renesas Peripheral Driver Library (RPDL)

Target MCU

User Application

Renesas Peripheral Driver Library Middleware, including drivers

CPU Peripherals Supported by the RPDL USB, Ethernet, CAN

Callback Functions

Low level library to configure and control peripherals.

Common API calls to facilitate easy coding

R_BSC_Control, R_TPU_Control, R_SCI_Control, etc

Configuration and access to interrupt events via callbacks

• Menu driven selection of pin functions

• Makes calls to Renesas Peripheral Driver Library

• Generates specific C code for device drivers

Quick Design Guide, Migration Application Notes and Middleware


The buffers are controlled using the Input Buffer

Control Registers (ICR). After reset the default

value for the register is “0” which means there is

no connection between the peripheral and the

pin on the MCU.

Quick Design Guide

Answers common questions

Highlights unique features

Warns of common mistakes

Emphasizes critical notes

“After writing to the SCKCR, further writing to the

same register before completion of the change in

frequency is ignored. In the case of continued writing

to the SCKCR, confirm that values read from the

SCKCR are actually the most recently written

values.”
