Dual-function
Function
-
Port 0 (P0):
• 8-bit I/O port.
• Functions as a real-time output port (4 bits × 2).
• Inputs and outputs can be specified bit by bit.
• The use of the pull-up resistors can be specified by software for the pins
in input mode together.
• Can drive a transistor.
PWM0
Port 1 (P1):
PWM1
• 8-bit I/O port.
ASCK2/SCK2
• Inputs and outputs can be specified bit by bit.
RxD2/SI2
TxD2/SO2
-
• The use of the pull-up resistors can be specified by software for the pins
in input mode together.
• Can drive LED.
NMI
Port 2 (P2):
INTP0
• 8-bit input-only port.
INTP1
INTP2/CI
INTP3
INTP4/ASCK/SCK1
• P20 does not function as a general-purpose port (nonmaskable
interrupt). However, the input level can be checked by an interrupt
service routine.
• The use of the pull-up resistors can be specified by software for pins
P22 to P27 (in units of 6 bits).
INTP5
• The P25/INTP4/ASCK/SCK1 pin functions as the SCK1 output pin by
SI0
CSIM1.
RxD/SI1
Port 3 (P3):
TxD/SO1
• 8-bit I/O port.
SCK0/SCL
• Inputs and outputs can be specified bit by bit.
SO0/SDA
TO0-TO3
• The use of the pull-up resistors can be specified by software for the pins
in input mode together.
AD0-AD7
Port 4 (P4):
• 8-bit I/O port.
• Inputs and outputs can be specified bit by bit.
• The use of the pull-up resistors can be specified by software for the pins
in the input mode together.
• Can drive LED.
A8-A15
Port 5 (P5):
• 8-bit I/O port.
• Inputs and outputs can be specified bit by bit.
• The use of the pull-up resistors can be specified by software for the pins
in the input mode together.
• Can drive LED.
