P31 to P34 function as a 4-bit I/O port. These pins also function as pins for external interrupt request input, timer
The following operation modes can be specified in 1-bit units.
P31 to P34 function as a 4-bit I/O port. P31 to P34 can be set to input or output port in 1-bit units using port
mode register 3 (PM3). Use of an on-chip pull-up resistor can be specified by pull-up resistor option register 3
(PU3).
P31 to P34 function as external interrupt request input, timer I/O, buzzer output, real-time counter output, and
manchester code output.

(b) TO00, TOH0, TOH1
These are the external interrupt request input pins for which the valid edge (rising edge, falling edge, or both
rising and falling edges) can be specified.
These are timer output pin.
This is a pin for inputting an external count clock to 16-bit timer/event counters 00 and is also for inputting a
capture trigger signal to the capture registers (CR000 or CR010) of 16-bit timer/event counters 00.
This is a pin for inputting a capture trigger signal to the capture register (CR000) of 16-bit timer/event
counters 00.
This is the pin for inputting an external count clock to 8-bit timer/event counter 52.
This is a buzzer output pin.
This is a real-time counter clock (32 kHz, divided) output pin.
This is a real-time counter clock (32 kHz, original oscillation) output pin.
RTC1HZ
This is a real-time counter correction clock (1 Hz) output pin.
MCGO
This is a Manchester code output pin.
