Interrupt Flag Status and Clear
Note: Depending on the fuse settings, various bits of the INTFLAG register can be set to one at startup. Therefore the user should clear those bits before using the corresponding interrupts.

Reserved
These bits are unused and reserved for future use. For compatibility with future devices, always write these bits to zero when this register is written. These bits will always return zero when read.
BOD33 Synchronization Ready
This flag is cleared by writing a one to it.
This flag is set on a zero-to-one transition of the BOD33 Synchronization Ready bit in the Status register (PCLKSR.B33SRDY) and will generate an interrupt request if INTENSET.B33SRDY is one.
Writing a zero to this bit has no effect.
Writing a one to this bit clears the BOD33 Synchronization Ready interrupt flag
BOD33 Detection
This flag is cleared by writing a one to it.
This flag is set on a zero-to-one transition of the BOD33 Detection bit in the Status register (PCLKSR.BOD33DET) and will generate an interrupt request if INTENSET.BOD33DET is one.
Writing a zero to this bit has no effect.
Writing a one to this bit clears the BOD33 Detection interrupt flag.
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.
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.
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.DFLLLCKC) 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.
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.
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.DFLLOOB) 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.
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.
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.
OSC32K Ready
This flag is cleared by writing a one to it.
This flag is set on a zero-to-one transition of the OSC32K Ready bit in the Status register (PCLKSR.OSC32KRDY) and will generate an interrupt request if INTENSET.OSC32KRDY is one.
Writing a zero to this bit has no effect.
Writing a one to this bit clears the OSC32K Ready interrupt flag.
XOSC32K Ready
This flag is cleared by writing a one to it.
This flag is set on a zero-to-one transition of the XOSC32K Ready bit in the Status register (PCLKSR.XOSC32KRDY) and will generate an interrupt request if INTENSET.XOSC32KRDY is one.
Writing a zero to this bit has no effect.
Writing a one to this bit clears the XOSC32K Ready interrupt flag.
XOSC Ready
This flag is cleared by writing a one to it.
This flag is set on a zero-to-one transition of the XOSC Ready bit in the Status register (PCLKSR.XOSCRDY) and will generate an interrupt request if INTENSET.XOSCRDY is one.
Writing a zero to this bit has no effect.
Writing a one to this bit clears the XOSC Ready interrupt flag.
