HX8346-A(T)240RGB x 320 dot, 262K color, TFT Mobile Single Chip Driver5.1.1.2 Serial Bus System InterfaceDATA SHEET V01The HX8346-A supports the serial bus interface in register-content mode by settingexternal pins “BS2, BS1” pins to “11”. The serial bus system interface mode isenabled through the chip select line (NCS), and accessed via a control consisting ofthe serial input data (SDI), serial output data (SDO), and the serial transfer clocksignal (DNC_SCL).As the chip select signal (NCS) goes low, the start byte needs to be transferred first.The start byte is made up of 6-bit bus device identification code, register select (RS)bit and read /write operation (RW) bit. The five upper bits of 6-bit bus deviceidentification code must be set to “01110”, and the least significant bit of theidentification code must be set as the external pin BS0 input as “ID”.The seventh bit (RS) of the start byte determine internal index register or register,GRAM accessing. It must be setting RS as “0” when write data to the index register orread the status, and it must be setting RS as “1” when write a command or GRAMdata. The read or write operation is selected by the eighth bit (RW). The Table 5.6 isspecified the function of RS and R/W bit.RS R/W Function0 0 Writes Indexes into IR1 0 Writes command into register or data into GRAM1 1 Reads command from register or data from GRAMTable 5. 6 The Function of RS and R/W BitHimax ConfidentialThis information contained herein is the exclusive property of Himax and shall not be distributed, reproduced, or disclosedin whole or in part without prior written permission of Himax.-P.44-July, 2007
