DDRAM stores display data of maximum 64 x 8 bits (Max 64 characters). DDRAM address is set in the address
counter as a hexadecimal number.
8.9 SEGMENT ICON RAM (ICONRAM)
ICONRAM has segment control data and segment pattern data. There are 2 ICONS pins (COMI0 & COMI1), which
have the same signal. So the icons on the same SEG are displayed at the same time. The number of icons is 80.

CGROM has 5 x 8 dot 256 characters. The Function Set instruction selects the 8 characters (00h - 07h) of CGROM
or CGRAM.
