Writing a zero to this bit has no effect.
Writing a one to this bit clears the BOD33 Detection interrupt flag.
z Bit 9 – BOD33RDY: BOD33 Ready
This flag is cleared by writing a one to it.
This flag is set on a zero-to-one transition of the BOD33 Ready bit in the Status register (PCLKSR.BOD33RDY)
and will generate an interrupt request if INTENSET.BOD33RDY is one.
Writing a zero to this bit has no effect.
Writing a one to this bit clears the BOD33 Ready interrupt flag.
z Bit 8 – DFLLRCS: DFLL Reference Clock Stopped
This flag is cleared by writing a one to it.
This flag is set on a zero-to-one transition of the DFLL Reference Clock Stopped bit in the Status register
(PCLKSR.DFLLRCS) and will generate an interrupt request if INTENSET.DFLLRCS is one.
Writing a zero to this bit has no effect.
Writing a one to this bit clears the DFLL Reference Clock Stopped interrupt flag.
z Bit 7 – DFLLLCKC: DFLL Lock Coarse
This flag is cleared by writing a one to it.
This flag is set on a zero-to-one transition of the DFLL Lock Coarse bit in the Status register (PCLKSR.DFLLL-
CKC) and will generate an interrupt request if INTENSET.DFLLLCKC is one.
Writing a zero to this bit has no effect.
Writing a one to this bit clears the DFLL Lock Coarse interrupt flag.
z Bit 6 – DFLLLCKF: DFLL Lock Fine
This flag is cleared by writing a one to it.
This flag is set on a zero-to-one transition of the DFLL Lock Fine bit in the Status register (PCLKSR.DFLLLCKF)
and will generate an interrupt request if INTENSET.DFLLLCKF is one.
Writing a zero to this bit has no effect.
Writing a one to this bit clears the DFLL Lock Fine interrupt flag.
z Bit 5 – DFLLOOB: DFLL Out Of Bounds
This flag is cleared by writing a one to it.
This flag is set on a zero-to-one transition of the DFLL Out Of Bounds bit in the Status register (PCLKSR.DFL-
LOOB) and will generate an interrupt request if INTENSET.DFLLOOB is one.
Writing a zero to this bit has no effect.
Writing a one to this bit clears the DFLL Out Of Bounds interrupt flag.
z Bit 4 – DFLLRDY: DFLL Ready
This flag is cleared by writing a one to it.
This flag is set on a zero-to-one transition of the DFLL Ready bit in the Status register (PCLKSR.DFLLRDY) and
will generate an interrupt request if INTENSET.DFLLRDY is one.
Writing a zero to this bit has no effect.
Writing a one to this bit clears the DFLL Ready interrupt flag.
z Bit 3 – OSC8MRDY: OSC8M Ready
This flag is cleared by writing a one to it.
This flag is set on a zero-to-one transition of the OSC8M Ready bit in the Status register (PCLKSR.OSC8MRDY)
and will generate an interrupt request if INTENSET.OSC8MRDY is one.
Writing a zero to this bit has no effect.
Writing a one to this bit clears the OSC8M Ready interrupt flag.
