KeyInt RTC Mode (RTCMODE = 0)
By the master command from Cortex−M3, internal
sequencer of RTC controls BACKUPB signal for isolation
and power off. KEYINT input or internal RTCINT signal
can generate power on sequence. Power off sequence using
BACKUPB is also available for activation of power off by
external source.
it is necessary to detect the drop of the voltage of VDDRTC
power supply, and set VDET to Low. (The RTC operation
stops).
