CVROE overrides the TRIS bit setting.
Selecting BGSEL<1:0> = 11 and CVRSS = 1 is invalid and will produce unpredictable results.
Unimplemented: Read as ‘0’
VREFSEL: Voltage Reference Select bit
1 = CV
0 = CV
BGSEL<1:0>: Band Gap Reference Source Select bits
11 = INTREF = V
10 = INTREF = 0.197V (nominal)
01 = INTREF = 0.59V (nominal)
00 = INTREF = 1.18V (nominal)
CVREN: Comparator Voltage Reference Enable bit
1 = Comparator voltage reference circuit powered on
0 = Comparator voltage reference circuit powered down
CVROE: Comparator Voltage Reference Output Enable bit
1 = Voltage level is output on CV
0 = Voltage level is disconnected from CV
CVRR: Comparator Voltage Reference Range Selection bit
1 = CV
0 = CV
CVRSS: Comparator Voltage Reference Source Selection bit
1 = Comparator voltage reference source, CV
0 = Comparator voltage reference source, CV
CVR<3:0> Comparator Voltage Reference Value Selection 0  CVR<3:0>  15 bits
