Bits 16, 17, 18, 19 – MCn Match or Capture Channel n Interrupt Flag

This flag is set after a match with the compare condition or once the CCn register contains a valid capture value, and will generate an interrupt request if INTENSET.MCn = ‘1’.

Writing a ‘0’ to one of these bits has no effect.

Writing a ‘1’ to one of these bits will clear the corresponding Match or Capture Channel n interrupt flag.

In Capture operation, this flag is automatically cleared when the CCn register is read.

Bits 14, 15 – FAULTn Non-Recoverable Fault n Interrupt Flag

This flag is set after a Non-Recoverable Fault n occurs, and will generate an interrupt request if INTENSET.FAULTn = ‘1’.

Writing a ‘0’ to this bit has no effect.

Writing a ‘1’ to this bit clears the Non-Recoverable Fault n interrupt flag.

Bits 12, 13 – FAULTx Recoverable Fault x Interrupt Flag

This flag is set after a Recoverable Fault x occurs, and will generate an interrupt request if INTENSET.FAULTx = ‘1’.

Writing a ‘0’ to this bit has no effect.

Writing a ‘1’ to this bit clears the Non-Recoverable Fault x interrupt flag.

Bit 11 – DFS Non-Recoverable Debug Fault State Interrupt Flag

This flag is set after a Debug Fault State occurs, and will generate an interrupt request if INTENSET.DFS = ‘1’.

Writing a ‘0’ to this bit has no effect.

Writing a ‘1’ to this bit clears the Debug Fault State interrupt flag.

Bit 10 – UFS Non-Recoverable Update Fault

This flag is set when the RAMP index changes and the Lock Update bit is set (CTRLBSET.LUPD = ‘1’), and will generate an interrupt request if INTENSET.UFS = ‘1’.

Writing a ‘0’ to this bit has no effect.

Writing a ‘1’ to this bit clears the Non-Recoverable Update Fault interrupt flag.

Bit 3 – ERR Error Interrupt Flag

This flag is set if a new capture occurs on a channel when the corresponding Match or Capture Channel x interrupt flag = ‘1’. This means that it is not possible to save the new capture value, and it will generate an interrupt request if INTENSET.ERR = ‘1’.

Writing a ‘0’ to this bit has no effect.

Writing a ‘1’ to this bit clears the Error Interrupt flag.

Bit 2 – CNT Counter Interrupt Flag

This flag is set after a counter event occurs, and it will generate an interrupt request if INTENSET.CNT = ‘1’.

Writing a ‘0’ to this bit has no effect.

Writing a ‘1’ to this bit clears the CNT Interrupt flag.

Bit 1 – TRG Retrigger Interrupt Flag

This flag is set after a counter retrigger occurs, and it will generate an interrupt request if INTENSET.TRG = ‘1’.

Writing a ‘0’ to this bit has no effect.

Writing a ‘1’ to this bit clears the Retrigger Interrupt flag.

Bit 0 – OVF Overflow Interrupt Flag

This flag is set after an overflow condition occurs, and it will generate an interrupt request if INTENSET.OVF = ‘1’.

Writing a ‘0’ to this bit has no effect.

Writing a ‘1’ to this bit clears the Overflow Interrupt flag.
