• PSEL: Prescaler Select
Select the prescaler divide-by output for the BOD Sampling mode.
• CSSEL: Clock Source Select
0: Selects the RCSYS as BOD Sampling clock source.
1: Selects the 32kHz clock as BOD Sampling clock source. Setting the CK32S bit to one in the PMCON register
(PMCON.CK32S) will select the RC32K oscillator as the 32 KHz clock source, and leaving it to zero will select the 32 KHz
crystal oscillator output.
• CEN: Clock Enable
Writing a zero to this bit will stop the BOD sampling clock.
Writing a one to this bit will start the BOD sampling clock.
0: The BOD Sampling clock is either disabled and stopped, or enabled but not yet stable.
1: The BOD Sampling clock is either enabled and stable, or disabled but not yet stopped.
