Pin Functions
When the corresponding bit in PTCNT0 is set to 1, port 5 pins can be used as PWM output pins
(ExPW5 and ExPW4). The relationship between register setting values and pin functions is as
follows.
• P57/TMO1_1/ExPW5
When the PW5S bit in PTCNT0 is set to 1, this pin can be used as an ExPW5 pin.
The pin function is switched as shown below according to the combination of the OS3 to OS0
bits in TCSR of the TMR1_1, the OE5 bit in PWOER of the PWM, the PW5S bit, and the
P57DDR bit.

• P56/TMO0_1/ExPW4
When the PW4S bit in PTCNT0 is set to 1, this pin can be used as an ExPW4 pin.
The pin function is switched as shown below according to the combination of the OS3 to OS0
bits in TCSR of the TMR0_1, the OE4 bit in PWOER of the PWM, the PW4S bit, and the
P56DDR bit.
