When the corresponding bit in PTCNT1 is cleared to 0, port 4 pins can be used as interrupt input
pins (IRQ7 to IRQ0). When the corresponding bit in PTCNT0 is set to 1, port 4 pins can be used
as PWM output pins (ExPW3 to ExPW0). The relationship between register setting values and pin
functions is as follows.
• P47/IRQ7/TMIY_0/ExPW3

• P46/IRQ6/TMIX_0/ExPW2

Pin function
When the IRQ7S bit in PTCNT1 is cleared to 0, this pin can be used as an IRQ7 pin.
When the PW3S bit in PTCNT0 is set to 1, this pin can be used as an ExPW3 pin.
The pin function is switched as shown below according to the combination of the OE3 bit in
PWOER of the PWM, the IRQ7S bit, the PW3S bit, and the P47DDR bit.
When the external clock is selected by the CKS2 to CKS0 bits in TCR of the TMRY_0, this
pin functions as a TMCIY input pin. When the CCLR1 and CCLR0 bits in TCR of the
TMRY_0 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 can be used as an IRQ6 pin.
When the PW2S bit in PTCNT0 is set to 1, this pin can be used as an ExPW2 pin.
The pin function is switched as shown below according to the combination of the OE2 bit in
PWOER of the PWM, the IRQ6S bit, the PW2S bit, and the P46DDR bit.
When the external clock is selected by the CKS2 to CKS0 bits in TCR of the TMRX_0, this
pin functions as a TMCIX input pin. When the CCLR1 and CCLR0 bits in TCR of the
TMRX_0 are both set to 1, this pin functions as a TMRIX input pin.
* When the IRQ7S bit in PTCNT1 is cleared to 0, this pin functions as the IRQ7 input pin.
