P51/
IRQ9
/RxDF
The pin function is switched as shown below according to the combination of the
enable/disable setting of the SCIF and the P51DDR 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. To use as the
IRQ9
input pin,
clear the P51DDR bit to 0.

The pin function is switched as shown below according to the combination of the
enable/disable setting of the SCIF and the P50DDR 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. To use as the
