There are a total of 128 character code registers, 32 characters per row for four rows.
Character Codes:
ROM/RAM - ROM/RAM mapping select
1 (set) – CH6-CH0 is mapped to the 16 RAM codes.
0 (clear) – CH6-CH0 is mapped to the 128 ROM/EPROM codes.
CH6-CH0
0 to 127 = ROM/EPROM codes.
0 to 15 = RAM codes. Codes 16 and higher are invalid.
