• P34/WUE12/MCCMDDIR/MCCSB
The pin function is switched as shown below according to the combination of the MCIF
operating mode and the P34DDR bit.
When the WUEM12 bit in WUEMR3 of the interrupt controller is cleared to 0, this pin can be
used as the WUE12 input pin. To use this pin as the WUE12 input pin, clear the P34DDR bit
to 0.
