Notes: 1. In the character display mode (SPR = 0 and GR = 0), RM = 1 is set and CGRAM is used. The
CGRAM font pattern is displayed using character codes set to the DDRAM as per the above
table.
2. In the graphics display mode (SPR = 0 and GR
=
1), the CGRAM bit map data is displayed
irrespective of the DDRAM set character code.
3. In the superimposed display mode (SPR = 1), the CGRAM bit map data is displayed.
4. When the memory bank switching bit generates ROM
=
0, CGRAM fonts for 16 character codes
"00"H to "0F"H can be displayed. When ROM
=
1, CGRAM fonts for 64 character codes "00"H to
"1F"H and "80"H to "9F"H can be displayed.
