P41DDR
Pin function
P40DDR
Pin function
When the IRQ1S bit in PTCNT1 is cleared to 0, this pin can be used as an IRQ1 pin.
The pin function is switched as shown below according to the combination of the IRQ1S bit
and the P41DDR bit.
When the ICICE bit in TIER of the FRT_1 is set to 1, this pin functions as an FTIC_1 input
pin.
When the IRQ0S bit in PTCNT1 is cleared to 0, this pin can be used as an IRQ0 pin.
The pin function is switched as shown below according to the combination of the IRQ0S bit
and the P40DDR bit.
When the ICIBE bit in TIER of the FRT_1 is set to 1, this pin functions as an FTIB_1 input
pin.
* When the IRQ1S bit in PTCNT1 is cleared to 0, this pin functions as the IRQ1 input pin.
* When the IRQ0S bit in PTCNT1 is cleared to 0, this pin functions as the IRQ0 input pin.
