Pin function
When the IRQ5S bit in PTCNT1 is cleared to 0, this pin can be used as an IRQ5 pin.
When the PW1S bit in PTCNT0 is set to 1, this pin can be used as an ExPW1 pin.
The pin function is switched as shown below according to the combination of the OE1 bit in
PWOER of the PWM, the IRQ5S bit, the PW1S bit, and the P45DDR bit.
When the external clock is selected by the CKS2 to CKS0 bits in TCR of the TMR0_0, this pin
functions as a TMCI0 input pin. When the CCLR1 and CCLR0 bits in TCR of the TMR0_0
are both set to 1, this pin functions as a TMRI0 input pin.
When the IRQ4S bit in PTCNT1 is cleared to 0, this pin can be used as an IRQ4 pin.
When the PW0S bit in PTCNT0 is set to 1, this pin can be used as an ExPW0 pin.
The pin function is switched as shown below according to the combination of the OE0 bit in
PWOER of the PWM, the IRQ4S bit, the PW0S bit, and the P44DDR bit.
When the external clock is selected by the CKS2 to CKS0 bits in TCR of the TMRY_1, this
pin functions as a TMCIY input pin. When the CCLR1 and CCLR0 bits in TCR of the
TMRY_1 are both set to 1, this pin functions as a TMRIY input pin.
* When the IRQ6S bit in PTCNT1 is cleared to 0, this pin functions as the IRQ6 input pin.
* When the IRQ5S bit in PTCNT1 is cleared to 0, this pin functions as the IRQ5 input pin.
