3.9 Character Display Position Control Command
This command can be used to set the character display start position in 32 steps in units of 3 dots in the horizontal
direction, and in 32 steps in units of 3 rows in the vertical direction (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).)
