CHAPTER 2 PIN FUNCTIONS
2.2.4 P30 to P34
P30 to P34 function as an I/O port. This port can also be used for timer I/O, real-time counter clock output, correction
clock output, clock output/buzzer output, and external interrupt request input.

The following operation modes can be specified in 1-bit units.
(1) Port mode
P30 to P34 function as an I/O port. P30 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).
(2) Control mode
P30 to P34 function as timer I/O, real-time counter clock output, correction clock output, clock output/buzzer output,
and external interrupt request input.
(a) TI00, TI01, TI03 TI06, TI07
These are the timer input pins of 16-bit timers 00, 01, 03, 06, and 07.
(b) TO00, TO01, TO03, TO06, TO07
These are the timer output pins of 16-bit timers 00, 01, 03, 06, and 07.
(c) RTCCL
This is a real-time counter clock (32 kHz, original oscillation) output pin.
(d) RTCDIV
This is a real-time counter clock (32 kHz, divided) output pin.
(e) RTC1HZ
This is a real-time counter correction clock (1 Hz) output pin.
(f) PCLBUZ0, PCLBUZ1
These are clock output/buzzer output pins.
(g) INTP1, INTP2, INTP3, INTP5, INTP8
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.
