• P56/IRQ14/PWX0/φ/EXCL
The pin function is switched as shown below according to the combination of the OEA bit in
DACR of PWMX, the EXCLE bit in LPWRCR, and the P56DDR bit.
When the ISS14 bit in ISSR16 is cleared to 0 and the IRQ14E bit in IER16 of the interrupt
controller is set to 1, this pin can be used as the IRQ14 input pin. To use this pin as the IRQ14
input pin, clear the P56DDR bit to 0.

• P53/IRQ11/RxD1
The pin function is switched as shown below according to the combination of the RE bit in
SCR of SCI_1, the SMIF bit in SCMR, and the P53DDR bit.
When the ISS11 bit in ISSR16 is cleared to 0 and the IRQ11E bit in IER16 of the interrupt
controller is set to 1, this pin can be used as the IRQ11 input pin. To use this pin as the IRQ11
input pin, clear the P53DDR bit to 0.
