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

CVREN: Comparator Voltage Reference Enable bit
1 = CVREF circuit powered on
0 = CVREF circuit powered down
CVROE: Comparator VREF Output Enable bit
1 = CVREF voltage level is output on CVREF pin
0 = CVREF voltage level is disconnected from CVREF pin
CVRR: Comparator VREF Range Selection bit
1 = CVRSRC range should be 0 to 0.625 CVRSRC with CVRSRC/24 step size
0 = CVRSRC range should be 0.25 to 0.719 CVRSRC with CVRSRC/32 step size
CVRSS: Comparator VREF Source Selection bit
1 = Comparator reference source CVRSRC = VREF+ – VREF-
0 = Comparator reference source CVRSRC = AVDD – AVSS
CVR<3:0>: Comparator VREF Value Selection 0 CVR<3:0> 15 bits
When CVRR = 1:
CVREF = (CVR<3:0>/ 24) (CVRSRC)
When CVRR = 0:
CVREF = 1/4 (CVRSRC) + (CVR<3:0>/32) (CVRSRC)
