8.7 Port 6
8.7.1 Overview
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), the timer Y
(TMRY) input pin (TMIY), timer connection I/O pins (HFBACKI, VSYNCI, VSYNCO,
VFBACKI, CLAMPO), key-sense interrupt input pins (KIN7 to KIN0), expansion A/D converter
input pins (CIN7 to CIN0), and external interrupt input pins (IRQ7, IRQ6). 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.
