8.8 Display Data RAM (DDRAM)
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.
8.10 Character Generator ROM (CGROM)
CGROM has 5 x 8 dot 256 characters. The Function Set instruction selects the 8 characters (00h - 07h) of CGROM
or CGRAM.
