7.1.3 8- and 9-bit Serial Interface
The 8-bit serial interface uses four pins /CS, SI, SCL, and A0 to enter commands and data. Meanwhile, the 9-bit serial
interface uses three pins /CS, SI and SCL for the same purpose.
Data read is not available in the serial interface. Data entered must be 8 bits for each time.
The relation between gray-scale data and data bus in the serial input is the same as that in the 8-bit parallel interface mode
at every gradation.
(1) 8-bit serial interface (4-line)
When entering data (parameters): A0= HIGH at the rising edge of the 8th SCL.
When entering command: A0= LOW at the rising edge of the 8th SCL
When entering reading command:
