2.13 Display Character Control Command (2-byte contiguous command)
This command specifies the character data and blinking data to be written to the video RAM.
When inputting this command, turn ON LC oscillation (if LC oscillation is turned OFF, no character can be
written to the video RAM).
Because this command is a 2-byte contiguous command, if character data are successively written without
the blinking data changed, the second character and those that follow can be abbreviated to the lower 8 bits
(D7 to D0). In this case, the write column address is automatically incremented (if a character is written to column
23 at the rightmost position, the next write address is automatically incremented to column 0 of the next line
(leftmost position)).
