Double-Width Display
When the font width bit (FW) is set, the width is 5 dots or 6 dots. When FW = 0, the font width is 5 dots
and can be displayed horizontally up to 12 digits. However, the spaces between characters should hold the
ITO wiring on the LCD glass. When FW = 1, the font width is 6 dots and can be displayed horizontally up
to 10 digits. However, when displaying double-width characters with the font in the CGROM, a special
double-width font is needed. In that case, a custom ROM is used.
Double-height characters can be displayed by setting the register in combination with the above double-
width display.
Note: This display can be performed with the custom CGROM.
