3.9 CHARACTER SIZE CONTROL COMMAND
command, requiring 16 bits for each command, even when continuously input).
This command specifies the character size (height and width at one time) for each row (this command is a 2-byte
(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

The character size is specified for each row. These bits are used to specify the row.
This bit is used to select either of two supported sizes.
