Pin function
When the IRQ3S bit in PTCNT1 is cleared to 0, this pin can be used as an IRQ3 pin.
The pin function is switched as shown below according to the combination of the IRQ3S bit
and the P43DDR bit.
When the external clock is selected by the CKS2 to CKS0 bits in TCR of the TMRX_1, this
pin functions as a TMCIX input pin. When the CCLR1 and CCLR0 bits in TCR of the
TMRX_1 are both set to 1, this pin functions as a TMRIX input pin.
When the IRQ2S bit in PTCNT1 is cleared to 0, this pin can be used as an IRQ2 pin.
The pin function is switched as shown below according to the combination of the IRQ2S bit
and the P42DDR bit.
When the external clock is selected by the CKS2 to CKS0 bits in TCR of the TMR0_1, this pin
functions as a TMCI0 input pin. When the CCLR1 and CCLR0 bits in TCR of the TMR0_1
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 functions as the IRQ4 input pin.
* When the IRQ3S bit in PTCNT1 is cleared to 0, this pin functions as the IRQ3 input pin.
* When the IRQ2S bit in PTCNT1 is cleared to 0, this pin functions as the IRQ2 input pin.
