Pin function
The pin function is switched as shown below according to the combination of the OEB bit in
DACR of PWMX and the P57DDR bit.
When the ISS15 bit in ISSR16 is cleared to 0 and the IRQ15E bit in IER16 of the interrupt
controller is set to 1, this pin can be used as the IRQ15 input pin. To use this pin as the IRQ15
input pin, clear the P57DDR bit to 0.
The pin function is switched as shown below according to the combination of the OEA bit in
DACR of PWMX 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.
The pin function is switched as shown below according to the combination of the RE bit in
SCR of SCI_2 and the P55DDR bit.
When the ISS13 bit in ISSR16 is cleared to 0 and the IRQ13E bit in IER16 of the interrupt
controller is set to 1, this pin can be used as the IRQ13 input pin. To use this pin as the IRQ13
input pin, clear the P55DDR bit to 0.
