3.10 Write Address Control Command
This command is used to specify a write address when characters are written to the display area (video RAM) of
12 rows and 24 columns (because this command is a 2-byte command, input of 16 bits is necessary when this
command is input more than once successively).
(1) With MSB first (The command is input from MSB (D15).)
