HD66724/HD66725
CGROM Bank Switching Function
The HD66724/HD66725 incorporate two pages of CGROM. Switching the memory bank using the
CGROM bank switching bit (ROM) can display a total of 432 font patterns. Multinational fonts, special
symbols, and icons can be displayed. Note that the number of fonts simultaneously displayed is CGROM:
240 + CGRAM: 16 when memory bank 0 is selected, and CGROM: 192 + CGRAM: 64 when memory
bank 1 is selected. Font displays for CGRAM (1) to (16) are used in common with memory bank 0 and
memory bank 1.
