Bits 5,4 – WINx Window x

This flag is set according to the Window x Interrupt Selection bit group in the WINCTRL register

(WINCTRL.WINTSELx) and will generate an interrupt if INTENCLR/SET.WINx is also one.

Writing a '0' to this bit has no effect.

Writing a '1' to this bit clears the Window x interrupt flag.

Bits 3,2,1,0 – COMPx Comparator x

Reading this bit returns the status of the Comparator x interrupt flag. If comparator x is not implemented,

COMPx always reads as zero.

This flag is set according to the Interrupt Selection bit group in the Comparator x Control register

(COMPCTRLx.INTSEL) and will generate an interrupt if INTENCLR/SET.COMPx is also one.

Writing a '0' to this bit has no effect.

Writing a '1' to this bit clears the Comparator x interrupt flag.
