Character Generator ROM (CGROM)

The Character Generator ROM stores 5x8-dot character patterns for 8-bit character codes. It stores 256 5x8-dot character

patterns which can be selected by 8-bit character code (Table 5). The first 16 patterns are multiplexed with the Character

Generator RAM (CGRAM). By using instruction to set OPR2 & OPR1, customer can use the patterns stored in CGRAM to

replace these 16 default patterns. The detailed setting is illustrated in Table 7. User-defined character patterns are also

supported by changing the content in mask-programmed ROM. Table 5 illustrated the relation between Character Codes and

Character Patterns.
