1. General Description The HX8238-A application note includes SPI commands, FPC pins, OLB resistance and application circuit. H-Sync (HSYNC), V-Sync (VSYNC), Data enable (DEN), and Clock (DOTCLK) from video decoder or other source.The interface follows digital 8-bit serial/24-bit parallel RGB, CCIR601 and CCIR656 input format.
HX8238-A is a single chip controller and driver LSI that integrated the power circuit. It can drive a maximum 960x240 dot graphics on a-TFT panel displays in 262K colors. HX8238-A has a low-voltage operation, 1.4 min. In addition, HX8238-A is equipped with a DC-DC converter control circuit that generates the supply voltage for source and gate drivers with minimum external components. A common voltage generation circuit is included to drive the TFT-display counter electrode. An integrated gamma control circuit is also included that can be adjusted by software commands to provide maximum flexibility and optimal display quality.

2.SPI commands setting
2.1 Serial Interface
The SPI is available through the chip select line (CSB), serial transfer clock line (SCK), serial data input (SDI), and serial data output (SDO). The Driver IC recognizes the start of data transfer at the falling edge of CSB input to initiate the transfer of start byte. It recognizes the end of data transfer at the rising edge of CSB input. The Driver IC is selected when the 6-bit chip address in the start byte transferred from the transmission device and the 6-bit device identification code assigned to the Driver IC are compared and both 6-bit data correspond. The identification code must be 011100. Two different chip addresses must be assigned to the Driver IC because the seventh bit of the start byte is assigned to a register select bit (RS). When RS = 0, index register write or status read is executed. When the RS = 1, instruction write. The eighth bit of the start byte is to specify read or write (R/W bit). The data are received when the R/W bit is 0, and are transmitted when the R/W bit is 1. After receiving the start byte, the Driver IC starts to transmit or receive data by byte. The data transmission adopts a format by which the MSB is first transmitted (9th SCK started). All Driver IC instructions consist of 16 bits and they are executed internally after two bytes are transmitted with the MSB first (IB15 to 0---9th ~24th SCK).

CPE: When CPE=0, internal charge pump circuit is shut down. When CPE=1, internal charge pump circuit is enabled.
REV: Displays all character and graphics display sections with reversal when REV = “1”. Since the grayscale level can be reversed, display of the same data is enabled on normally white and normally black panels. Source output level is indicated below.

PINV: When PINV=0, POL output is same phase with internal VCOM signal. When PINV=1, POL output phase is reversed with VCOM signal.
BGR: Selects the <R><G><B> arrangement. When BGR = “0” <R><G><B> color is assigned from S0.When BGR = “1” <B><G><R> color is assigned from S0.
SM: Change the division of gate driver. When SM = “0”, odd/even division (interlace mode) is selected. When SM = “1”, upper/lower division is selected. Select the division mode according to the mounting method.
TB: Selects the output shift direction of the gate driver. When TB = “1”, G0 shifts to G239. When TB = “0”, G239 shifts to G0.
RL: Selects the output shift direction of the source driver. When RL = “1”, S0 shifts to S959 and <R><G><B> color is assigned from S0. When RL = “0”, S959 shifts to S0 and <R><G><B> color is assigned from S959. Set RL bit and BGR bit when changing the dot order of R, G and B.
Note: The default setting of register bits REV, BGR, TB and RL are defined by the logic stage of corresponding hardware pins. These bits will override the hardware setting once software command was sent to set the bits.
