Port 6 is an 8-bit I/O port. Port 6 pins also function as the 16-bit free-running timer (FRT) I/O pins
(FTOA, FTOB, FTIA to FTID, FTCI), timer X (TMRX) I/O pins (TMOX, TMIX) (H8S/2138
Group only), the timer Y (TMRY) input pin (TMIY), timer connection I/O pins (HFBACKI,
VSYNCI, VSYNCO, VFBACKI, CLAMPO) (H8S/2138 Group only), key-sense interrupt input
pins (KIN7 to KIN0), expansion A/D converter input pins (CIN7 to CIN0), and external interrupt
input pins (IRQ7, IRQ6). In the H8S/2138 Group, the port 6 input level can be switched in four
stages. Port 6 pin functions are the same in all operating modes.
Figure 8.14 shows the port 6 pin configuration.
