Notes: 1. In the character display mode (GR = 0), CGRAM font pattern is displayed using character codes
set to DDRAM as per the above table. In the graphics display mode (GR = 1), CGRAM data is
displayed irrespective of the DDRAM set data (character code).
2. 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.
