1: The BOD33 Detection interrupt is enabled, and an interrupt request will be generated when the BOD33 Detec-
tion Interrupt flag is set.

Writing a zero to this bit has no effect.

Writing a one to this bit will clear the BOD33 Detection Interrupt Enable bit, which disables the BOD33 Detection 
interrupt.

z

Bit 9 – BOD33RDY: BOD33 Ready Interrupt Enable
0: The BOD33 Ready interrupt is disabled. 

1: The BOD33 Ready interrupt is enabled, and an interrupt request will be generated when the BOD33 Ready 
Interrupt flag is set.

Writing a zero to this bit has no effect.

Writing a one to this bit will clear the BOD33 Ready Interrupt Enable bit, which disables the BOD33 Ready 
interrupt.

z

Bit 8 – DFLLRCS: DFLL Reference Clock Stopped Interrupt Enable
0: The DFLL Reference Clock Stopped interrupt is disabled. 

1: The DFLL Reference Clock Stopped interrupt is enabled, and an interrupt request will be generated when the 
DFLL Reference Clock Stopped Interrupt flag is set.

Writing a zero to this bit has no effect.

Writing a one to this bit will clear the DFLL Reference Clock Stopped Interrupt Enable bit, which disables the DFLL 
Reference Clock Stopped interrupt. 

z

Bit 7 – DFLLLCKC: DFLL Lock Coarse Interrupt Enable
0: The DFLL Lock Coarse interrupt is disabled. 

1: The DFLL Lock Coarse interrupt is enabled, and an interrupt request will be generated when the DFLL Lock 
Coarse Interrupt flag is set.

Writing a zero to this bit has no effect.

Writing a one to this bit will clear the DFLL Lock Coarse Interrupt Enable bit, which disables the DFLL Lock Coarse 
interrupt.

z

Bit 6 – DFLLLCKF: DFLL Lock Fine Interrupt Enable
0: The DFLL Lock Fine interrupt is disabled. 

1: The DFLL Lock Fine interrupt is enabled, and an interrupt request will be generated when the DFLL Lock Fine 
Interrupt flag is set.

Writing a zero to this bit has no effect.

Writing a one to this bit will clear the DFLL Lock Fine Interrupt Enable bit, which disables the DFLL Lock Fine 
interrupt.

z

Bit 5 – DFLLOOB: DFLL Out Of Bounds Interrupt Enable
0: The DFLL Out Of Bounds interrupt is disabled. 

1: The DFLL Out Of Bounds interrupt is enabled, and an interrupt request will be generated when the DFLL Out Of 
Bounds Interrupt flag is set.

Writing a zero to this bit has no effect.

Writing a one to this bit will clear the DFLL Out Of Bounds Interrupt Enable bit, which disables the DFLL Out Of 
Bounds interrupt.

z

Bit 4 – DFLLRDY: DFLL Ready Interrupt Enable
0: The DFLL Ready interrupt is disabled.

1: The DFLL Ready interrupt is enabled, and an interrupt request will be generated when the DFLL Ready Interrupt 
flag is set.

Writing a zero to this bit has no effect.

Writing a one to this bit will clear the DFLL Ready Interrupt Enable bit, which disables the DFLL Ready interrupt.
