R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown
bit 15 CMSIDL: Stop in Idle Mode bit
1 = Discontinue operation of all comparators when device enters Idle mode
0 = Continue operation of all comparators in Idle mode
bit 14-11 Unimplemented: Read as ‘0’
bit 10 C3EVT: Comparator 3 Event Status bit
1 = Comparator event occurred
0 = Comparator event did not occur
