Channel Interrupt Flags — These bits signal pending channel interrupts. They can only be set by the RISC
core (see SIF instruction on page 10-449). Each flag can be cleared by writing a "1" to its bit location.
Unimplemented interrupt flags will always read "0". Section “Interrupts” of the device overview for a list of
implemented Interrupts.
Read:
0 Channel interrupt is not pending
1 Channel interrupt is pending if XGIE is set
Write:
0 No effect
1 Clears the interrupt flag
