Legend:
R = Readable bit
-n = Value at POR
W = Writable bit
‘1’ = Bit is set
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared
x = Bit is unknown

bit 7
bit 6
bit 5
bit 4-0
Unimplemented: Read as ‘0’
CVREN: Comparator Voltage Reference Enable bit
1 = CVREF circuit is powered on
0 = CVREF circuit is powered down
CVROE: Comparator VREF Output Enable bit
1 = CVREF voltage level is output on the CVREF pin
0 = CVREF voltage level is disconnected from the CVREF pin
CVRSS: Comparator VREF Source Selection bit
1 = Comparator reference source, CVRSRC = VREF+ – VREF-
0 = Comparator reference source, CVRSRC = AVDD – AVSS
CVR<4:0>: Comparator VREF Value Selection 0 ≤ CVR<4:0> ≤ 31 bits
When CVRSS = 1:
CVREF = (VREF-) + (CVR<4:0>/32) • (VREF+ – VREF-)
When CVRSS = 0:
CVREF = (AVSS) + (CVR<4:0>/32) • (AVDD – AVSS)
