Bits 7:5 – 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.

Writing a zero to this bit has no effect.
Writing a one to this bit clears the Window 0 interrupt flag.

Bits 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.
