(4) PF1/IRQ9/PWMU1A

The pin function is switched as shown below according to the combination of the register setting

of the PWMU 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.
