Section 8 I/O Ports
8.7
Port 6 is an 8-bit I/O port. Port 6 pins also function as the FRT I/O pins, TMR_X I/O pins, the
TMR_Y input pin, timer connection I/O pins, key-sense interrupt input pins, expansion A/D
converter input pins, and external interrupt input pins. The port 6 input level can be switched in
four stages. Port 6 pin functions are the same in all operating modes. For details on the system
control register 2 (SYSCR2), refer to section 18, Host Interface X-Bus Interface (XBS). Port 6 has
the following registers.
