2. When Using One 4-M EPROM
2.1 Full-size Character (Level-1 Kanji Set, Non-Kanji) (FCGROM-1)
11 x 12 dots, up to 4064 types (not including 32 types of CGRAM (character code: 0000 to 001F))
EPROM: HN27C4001G x one (address: $0 to $1FFFF)
Divide character pattern into six left-half dots (A16 = 0) and five right-half dots (A16 = 1)
EPROM addresses A18 to A 0 designate the "0 + full-size character code (C12) + left/right distinction
bit + full-size character code (C11 to C0) + line position" (C12 of the full-size character code is used as
an EPROM address A17)
Write "0" into I/0s 7 and 6 of the left-half character pattern (A16 = 0)
Write "0" into I/0s 7, 6 and 5 of the right-half character pattern (A16 = 1)
When A3, A2, A1, or A0 = $C to $F (1100 to 1111), write "0" into I/Os 7 to 0
Write "0" into $0 to $1FF, and $10000 to $101FF (corresponding to the CGRAM character codes 0000
to 001F) (The data of $0 to $1FF, and $10000 to $101FF are ignored)
