3.26.4.1 Entering the PCM state
off. To enter the Power Cut Mode, the following procedure must be observed to prepare for
operation after exiting the Power Cut Mode, to define the external pin states during the
Power Cut Mode, and to ensure proper mode transition.
In the Power Cut Mode, power supplies to the internal circuits including the CPU are cut

The internal RTC, an external key or an external interrupt can be selected as a
For entering the PCM state, the program must be executing in the internal
RAM.
Before entering the PCM mode, stop all functions that may interfere with the
mode transition operation.
Set the backup registers to fix the state of each pin during the PCM state.
In the PCM state, the port states are controlled by the backup registers in the
PMC.
PC2 should be set as the PWE pin.
Only the CKE pin (which is controlled by SDRAM) allows the pin state on
exiting the PCM state to be different from the pin state after system reset. For
details, refer to 3.26.4.3.
