Pin function
When the IRQ1S bit in PTCNT1 is set to 1, this pin can be used as the ExIRQ1 pin.
The pin function is switched as shown below according to the operating mode, the IRQ1S bit,
and the P31DDR bit.
When the IRQ0S bit in PTCNT1 is set to 1, this pin can be used as the ExIRQ0 pin.
The pin function is switched as shown below according to the operating mode, the IRQ0S bit,
and the P30DDR bit.
* When the IRQ1S bit in PTCNT1 is set to 1, this pin functions as the ExIRQ1 input pin.
* When the IRQ0S bit in PTCNT1 is set to 1, this pin functions as the ExIRQ0 input pin.
