Pin function
P33/WUE11/MCDATDIR/MCCSA
The pin function is switched as shown below according to the combination of the MCIF
operating mode and the P33DDR bit.
When the WUEM11 bit in WUEMR3 of the interrupt controller is cleared to 0, this pin can be
used as the WUE11 input pin. To use this pin as the WUE11 input pin, clear the P33DDR bit
to 0.
P32/WUE10/MCDAT/MCRxD
The pin function is switched as shown below according to the combination of the MCIF
operating mode and the P32DDR bit.
When the WUEM10 bit in WUEMR3 of the interrupt controller is cleared to 0, this pin can be
used as the WUE10 input pin. To use this pin as the WUE10 input pin, clear the P32DDR bit
to 0.
