S6B33A2 PRELIMINARY VER 1.3 128 RGB SEGMENT & 129 COMMON DRIVER FOR 4,096 COLOR STN LCD
Set Display Data Length
This Instruction is only used in 3-pin SPI MPU interface mode(PS=”L”, MPU[1]=”L”). It consists of two
continuous commands, the first byte control the data direction(write mode only) and inform the LCD driver the
second and third bytes will be number of data bytes will be write. When DI is not used, the Display Data Length
