Set Column Address

The range of column address is 0…131. The parameter is separated into 2 instructions. The column address is increased

(+1) after each byte of display data access (read/write). This allows MPU accessing DDRAM content continuously. This

feature stops at the end of each page (Column Address “83h”).

Write Data

8-bit data of Display Data from the microprocessor can be written to the RAM location specified by the column address and

page address. The column address is increased by 1 automatically so that the microprocessor can continuously write data

to the addressed page. During auto-increment, the column address wraps to 0 after the last column is written.
