3-Line SPI Mode (PS0 = "L", PS1 = "L",PS2= "L")
To write data to the DDRAM, send Data Direction Command in 3-Line SPI mode. Data is latched at the rising edge of
SCLK. And the DDRAM column address pointer will be increased by one automatically.
(1) Set Page and Column Address.
(2) Set DDC (Data Direction Command) and No. of Data Bytes.
(3) This figure is example for 104 Data bytes to be transferred.
This command is used in 3-Line SPI mode only. It will be two continuous commands, the first byte controls the data
direction and informs the LCD driver the second byte will be number of data bytes will be write. After these two commands
sending out, the following messages will be data. If data is stopped in transmitting, it is not valid data.
New data will be transferred serially with most significant bit first.
NOTE: In spite of transmission of data, if CSB is disabling, state terminates abnormally. Next state is initialized.
