• LPBGRDY:
0: Low Power Bandgap not enabled or not ready.
1: Low Power Bandgap is stable and ready to be used as voltage reference source.
• RC1MRDY:
0: RC1M oscillator not enabled or not ready.
1: RC1M oscillator is stable and ready to be used as clock source.
• SSWRDY: Buck voltage regulator has stopped switching:
0: Buck voltage regulator has not requested to stop switching or the stop switching request is not yet acknowledged.
1: Buck voltage regulator has stopped switching after a stop switching request.
This bit should be read only when the switching regulator feature is used.
• BOD18SYNRDY:
1: No BOD18 synchronization is ongoing.
0: A BOD18 synchronization is ongoing.
• BOD33SYNRDY:
1: No BOD33 synchronization is ongoing.
0: A BOD33 synchronization is ongoing.
• BOD18DET:
0: No BOD18 Event.
1: BOD18 has detected that power supply is going below BOD18 reference value.
• BOD33DET:
0: No BOD33 Event.
1: BOD33 has detected that power supply is going below BOD33 reference value.
• RC32KSAT:
0: The RC32K autocalibration has not saturated the FINE value.
