Description
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
Power Cut Abort Enable
0: Power Cut occurs during a low-battery alert
1: Power Cut is aborted
32-kHz Oscillator Enable
0: Disabled
1: Enabled
This bit must be enabled to use the Hibernation module. If a crystal is
used, then software should wait 20 ms after setting this bit to allow the
crystal to power up and stabilize.
LOW BAT Monitoring Enable
0: Disabled
1: Enabled
When set, low battery voltage detection is enabled.
External WAKE Pin Enable
0: Disabled
1: Enabled
When set, an external event on the WAKE pin will re-power the device.
RTC Wake-up Enable
0: Disabled
1: Enabled
When set, an RTC match event (RTC0 or RTC1) will re-power the device
based on the RTC counter value matching the corresponding match
register 0 or 1.
