Figure 7-10: Character Width Greater Than One Byte Wide ([FX]=9)
Note: The RA8835A series does not automatically insert spaces between characters. If the displayed
character size is 8 pixels or less and the space between character origins is nine pixels or
more, the bitmap must use two bytes per row, even though the character image requires only
one.
