Character Generator ROM (CGROM)
The CGROM generates character patterns (5
×
8 dots, 240 patterns) from the 8-bit character code signals in the
DDRAM. The bank switching pin (ROM1S) can switch to the other ROM that generates character patterns (5
×
8
dots, 240 patterns), allowing a total of 480 characters to be controlled.
When the 8-bit character code corresponding to a character pattern in the CGROM is written in the DDRAM, the
character pattern is displayed in the display position specified by the DDRAM address.
Character codes 10 to FF are contained in the ROM area in the CG ROM.
The general character generator ROM codes are 01/11/21.
The relationship between character codes and general purpose character patterns in Bank0 (ROM0) and Bank1
(ROM1) are indicated in Table 2-1 and Table 2-2, respectively.
