An external interrupt is used to wake up from the Power Cut Mode.

PMCCTL<PCM_ON> should be cleared by using PMCRES<RES_PCMON>.
After a system reset, the DMCCKE pin is always initialized to the “H” level. Therefore, if SDRAM has been set
to self-refresh mode before entering the Power Cut Mode, the self-refresh mode will be cleared when the
DMCCKE pin is initialized to the “H” level after wake-up from the Power Cut Mode. To avoid this situation, it
is possible only for the DMCCKE pin, which controls SDRAM, to specify different pin levels after a system
reset and after wake-up from the Power Cut Mode. The DMCCKE pin level after wake-up from the Power Cut
Mode can be set in the relevant PMC register.
