•Data format

Serial data is transmitted using four-line clock synchronous transmission. Serial data with a length of eight bits is

input synchronized to SCK. If C / D is HIGH at the rise of the 8 × nth clock of SCK, the serial data is recognized as a

command, and if C / D is LOW, the serial data is recognized as display data.

Serial data is input sequentially, starting from the MSB.
