These are 6-bit I/O ports. Besides serving as I/O ports, they function as a timer I/O, clock output, and buzzer output.
The following operating modes can be specified in 1-bit units.
This is an A/D converter reference voltage input pin.
When no A/D converter is used, connect this pin directly to V
This is an analog power supply pin of A/D converter. Always use the same potential as that of the V
This is a ground potential pin of A/D converter. Always use the same potential as that of the V

Port 7 functions as a 6-bit I/O port. They can be specified as an input port or output port in 1-bit units with port
mode register 7 (PM7). On-chip pull-up resistors can be used by setting pull-up resistor option register 7 (PU7).
P70 and P71 are also 16-bit timer/event counter 0 capture trigger signal input pins with a valid edge input.
Port 7 functions as timer I/O, clock output, and buzzer output.
External count clock input pin to 16-bit timer/event counter 0 and capture trigger signal input pin to 16-bit
timer/event counter capture register (CR00, CR01).
Capture trigger signal input pin to 16-bit timer/event counter 0 capture register (CR00).
External count clock input pins to 8-bit timer/event counters 50 and 51.
