Bit 7 – DFLLLCKC DFLL Lock Coarse Interrupt Enable
Writing a zero to this bit has no effect.
Writing a one to this bit will set the DFLL Lock Coarse Interrupt Enable bit, which enables the DFLL Lock
Coarse interrupt.
Value Description
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.
Bit 6 – DFLLLCKF DFLL Lock Fine Interrupt Enable
Writing a zero to this bit has no effect.
Writing a one to this bit will set the DFLL Lock Fine Interrupt Disable/Enable bit, disable the DFLL Lock
Fine interrupt and set the corresponding interrupt request.
Value Description
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.
Bit 5 – DFLLOOB DFLL Out Of Bounds Interrupt Enable
Writing a zero to this bit has no effect.
Writing a one to this bit will set the DFLL Out Of Bounds Interrupt Enable bit, which enables the DFLL Out
Of Bounds interrupt.
Value Description
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.
Bit 4 – DFLLRDY DFLL Ready Interrupt Enable
Writing a zero to this bit has no effect.
Writing a one to this bit will set the DFLL Ready Interrupt Enable bit, which enables the DFLL Ready
interrupt and set the corresponding interrupt request.
Value Description
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.
Bit 3 – OSC8MRDY OSC8M Ready Interrupt Enable
Writing a zero to this bit has no effect.
Writing a one to this bit will set the OSC8M Ready Interrupt Enable bit, which enables the OSC8M Ready
interrupt.
Value Description
0
The OSC8M Ready interrupt is disabled.
1
The OSC8M Ready interrupt is enabled, and an interrupt request will be generated when the
OSC8M Ready Interrupt flag is set.
