8.11.1
Port A is an 8-bit I/O port. Port A pins also function as keyboard buffer controller I/O pins
(PS2AC, PS2AD, PS2BC, PS2BD, PS2CC, PS2CD) (H8S/2148 Group and H8S/2147N only),
key-sense interrupt input pins (KIN15 to KIN8), expansion A/D converter input pins (CIN15 to
CIN8), and address output pins (A23 to A16). Port A pin functions are the same in all operating
modes. Figure 8.18 shows the port A pin configuration.
