HD66730/HD66731
Relationship between Character Codes (DDRAM), CGRAM Addresses, and Display
Characters
Full size character codes H'000 to H'007 can be used to access 8 character patterns in the CGRAM. Since
each character pattern can be displayed up to 12 × 13 dots, CGRAM patterns can be displayed immediately
next to each other (to the right, left, top, or bottom) without any character spaces between them. Table 6
shows the correspondence between CGRAM addresses and full-size character codes for access of the
CGRAM by the MPU.
