Graphics Display Function
The HD66728 has a character display mode (SPR = 0 and GR = 0) where the CGRAM or CGROM is used
to display font patterns, a graphics display mode (SPR = 0 and GR = 1) where the bit pattern data is set to
the CGRAM to display given patterns, and a superimposed display mode (SPR = 1) which displays both
display modes combined. In the character display mode, characters can easily be provided by sending one-
byte-per-character character codes to the DDRAM, but any pattern cannot be displayed. In the graphics
display mode or superimposed mode, all bit pattern data to be displayed must be sent although any pattern
can be displayed. The HD66728 supports these three modes which can easily be switched using the GR bit
and SPR bit.
In the graphics display mode, kanji characters, special symbols, and graphics icons can be displayed. Up to
112 x 80-dot display is allowed using the CGRAM. Thus, for a 12 x 13-dot kanji font, up to a 6-line x 9-
character kanji display, and for a 14 x 15-dot kanji font, up to a 6-line x 8-character kanji display, and for a
16 x 16-dot kanji font, up to a 5-line x 6-character kanji display are allowed.
