Pin function
P32DDR
Pin function
When the IRQ3S bit in PTCNT1 is set to 1, this pin can be used as the ExIRQ3 pin.
The pin function is switched as shown below according to the operating mode, the IRQ3S bit,
and the P33DDR bit.
When the IRQ2S bit in PTCNT1 is set to 1, this pin can be used as the ExIRQ2 pin.
The pin function is switched as shown below according to the operating mode, the IRQ2S bit,
and the P32DDR bit.
* When the IRQ3S bit in PTCNT1 is set to 1, this pin functions as the ExIRQ3 input pin.
* When the IRQ2S bit in PTCNT1 is set to 1, this pin functions as the ExIRQ2 input pin.
