• 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.
