Legend:
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 15-8 Unimplemented: Read as 0
bit 7 CVREN: Comparator Voltage Reference Enable bit
1 = CV
REF circuit is powered on
0 = CV
REF circuit is powered down
bit 6 CVROE: Comparator VREF Output Enable bit
1 = CVREF voltage level is output on the CV REF pin
0 = CV
REF voltage level is disconnected from the CVREF pin
bit 5 CVRR: Comparator V
REF Range Selection bit
1 = CV
RSRC range should be 0 to 0.625 CV RSRC with CV RSRC/24 step-size
0 = CV
RSRC range should be 0.25 to 0.719 CV RSRC with CV RSRC/32 step-size
bit 4 CVRSS: Comparator V REF Source Selection bit
1 = Comparator reference source, CV RSRC = V REF+  VREF-
0 = Comparator reference source, CV
RSRC = AVDD  AVSS
bit 3-0 CVR<3:0>: Comparator VREF Value Selection 0  CVR<3:0>  15 bits
When CVRR = 1:
CV REF = (CVR<3:0>/24)  (CV RSRC)
When CVRR = 0:
CV REF = 1/4  (CV RSRC) + (CVR<3:0>/32)  (CV RSRC)
