(4) PF1/IRQ9/PWMU1A
The pin function is switched as shown below according to the combination of the PWM1E bit in
PWMOUTCR of PWMU_A and the PF1DDR bit. When the ISS9 bit in ISSR16 is cleared to 0
and the IRQ9E bit in IER16 of the interrupt controller is set to 1, this pin can be used as the IRQ9
input pin.

(5) PF0/IRQ8/PWMU0A
The pin function is switched as shown below according to the combination of the PWM0E bit in
PWMOUTCR of PWMU_A and the PF0DDR bit. When the ISS8 bit in ISSR16 is cleared to 0
and the IRQ8E bit in IER16 of the interrupt controller is set to 1, this pin can be used as the IRQ8
input pin.
