In CGRAM, the user can rewrite character by program. For 5×8 dots, eight character patterns can be
written, and for 5×10 dots, four character patterns can be written.
Write into DDRAM the character code at the addresses shown as the left column of table 1. To show
the character patterns stored in CGRAM.
