Port 0 (P0):
8-bit I/O port
Can be used as real-time output port (4 bits
×
2).
Can be set in input or output mode bitwise.
Pins set in input mode can be connected to internal pull-up
resistors by software.
Can drive transistor.

Port 4 (P4):
8-bit I/O port
Can be set in input or output mode bitwise.
Pins set in input mode can be connected to internal pull-up
resistors by software.
Can drive LEDs.
P50 to P57
I/O
A8 to A15
Port 5 (P5):
8-bit I/O port
Can be set in input or output mode bitwise.
Pins set in input mode can be connected to internal pull-up
resistors by software.
Can drive LEDs.
Port 1 (P1):
8-bit I/O port
Can be set in input or output mode bitwise.
Pins set in input mode can be connected to internal pull-up
resistors by software.
Can drive LEDs.
Port 2 (P2):
8-bit input port
P20 cannot be used as general-purpose port pin (non-maskable
interrupt). However, its input level can be checked by interrupt
routine.
P22 through P27 can be connected to internal pull-up resistors
by software in 6-bit units.
P25/INTP4/ASCK/SCK1 pin can operate as SCK1 output pin
if so specified by CSIM1.
Port 3 (P3):
8-bit I/O port
Can be set in input or output mode bitwise.
Pins set in input mode can be connected to internal pull-up
resistors by software.
