Port 3 (P3):
8-bit I/O port.
Input and output can be specified in 1-bit units.
The use of on-chip pull-up resistors can be simultaneously specified by
software for all pins in input mode.
The use of the N-ch open drain can be specified for pins P32 and P33.

Can be used as a real-time output port (4 bits
×
2).
Input and output can be specified by 1-bit units.
The use of on-chip pull-up resistors can be simultaneously specified by
software for all pins in input mode.
Can drive transistors.

Port 4 (P4):
8-bit I/O port.
Input and output can be specified in 1-bit units.
The use of on-chip pull-up resistors can be simultaneously specified by
software for all pins in input mode.
Can drive LEDs.
P50 to P57

A8 to A15
Port 5 (P5):
8-bit I/O port.
Input and output can be specified in 1-bit units.
The use of on-chip pull-up resistors can be simultaneously specified by
software for all pins in input mode.
Can drive LEDs.
Port 2 (P2):
8-bit input port.
P20 does not function as a general-purpose port (non-maskable interrupt).
However, the input level can be checked by an interrupt service routine.
The use of on-chip pull-up resistors can be specified by software for pins
P22 to P27 (in 6-bit units).
The P25/INTP4/ASCK/SCK1 pin functions as the SCK1 output pin by a
CSIM1 specification.
Port 1 (P1):
8-bit I/O port.
Input and output can be specified in 1-bit units.
The use of on-chip pull-up resistors can be simultaneously specified by
software for all pins in input mode.
Can drive LEDs.
