P20 to P27 function as an 8-bit I/O port. These pins also function as A/D converter analog input.
The following operation modes can be specified in 1-bit units.
P30 and P31 function as a 2-bit I/O port. These pins also function as external interrupt request input, timer I/O,
The following operation modes can be specified in 1-bit units.

P20 to P27 function as an 8-bit I/O port. P20 to P27 can be set to input or output port in 1-bit units using port
mode register 2 (PM2).
P20 to P27 function as A/D converter analog input pins (ANI0 to ANI7). When using these pins as analog input
pins, see 10.7 (6) ANI0/P20 to ANI7/P27.
Caution ANI0/P20 to ANI7/P27 are set in the digital input (general-purpose port) mode after release of
P30 and P31 function as a 2-bit I/O port. P30 and P31 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).
P30 and P31 function as external interrupt request input, timer I/O, and real-time counter correction clock output.
(a) INTP3, INTP4
TO01, TO02
These are the timer output pins of 16-bit timers 01 and 02.
INTP5
This is an external interrupt request input pin for which the valid edge (rising edge, falling edge, or both rising
and falling edges) can be specified.
This is a real-time counter clock (32 kHz, divided) output pin.
RTCCL
This is a real-time counter clock (32 kHz, original oscillation) output pin.
Cautions 1. To use P10/SCK00 and P12/SO00/TxD0 as general-purpose ports, set serial
