3.7 WRITE ADDRESS CONTROL COMMAND
This command specifies the address at which a character is written in the display area (video RAM) of 12 rows
×
24 columns
(this command is a 2-byte command, requiring 16 bits for each command, even when continuously input).
(1) For MSB-first transfer (Command bits are input starting from the MSB (D15).)

(2) For LSB-first transfer (Command bits are input starting from the LSB (D0). The function of each bit is the same as
that for MSB-first transfer.)
Column write address specification bits
The display area has 24 columns. These bits are used to specify the column in which a character is to be written.
Row write address specification bits
The display area has 12 rows. These bits are used to specify the row in which a character is to be written.
