69-74 SEG1-26 — LCD SEGMENT output
(69*-73*) P85-80/D5-0 Note: Since RH-IX0189AWZZ is a 24-pin LCD, SEG0 of LCD is connected to SEG7 of
microcomputer output terminal (sequential connection up to SEG26).
75-100 SEG25-0 — LCD SEGMENT output
(94*-100*) Note: Since RH-IX0189AWZZ is a 24-pin LCD, SEG0 of LCD is connected to SEG7 of
microcomputer output terminal (sequential connection up to SEG26).
Pin No.
In this unit, the terminal with asterisk mark (*) is (open) terminal which is not connected to the outside.
