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 7 (P7):
8-bit I/O port
Can be set in input or output mode bitwise.
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.
Port6 (P6):
P60 through P63 is dedicated ports for output.
P66 and P67 can be set in input or output mode bitwise.
Pins set in input mode can be connected to internal pull-up
resistors by software.
