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
32-kHz Oscillator Enable
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 Battery Monitoring Enable
When set, low battery voltage detection is enabled (VBAT < 2.35 V).
External WAKE Pin Enable
When set, an external event on the WAKE pin will re-power the device.
