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 15-11
bit 10
bit 9-8
bit 7
bit 6
bit 5
bit 4-0
Unimplemented: Read as ‘0’
CVREFP: Comparator Voltage Reference Select bit (valid only when CREF is ‘1’)
1 = VREF+ is used as a reference voltage to the comparators
0 = The CVRx (5-bit DAC) within this module provides the reference voltage to the comparators
CVREFM<1:0>: Comparator Voltage Band Gap Reference Source Select bits
(valid only when CCH<1:0> = 11)
00 = Band gap voltage is provided as an input to the comparators
01 = Band gap voltage, divided by two, is provided as an input to the comparators
10 = Reserved
11 = VREF+ pin is provided as an input to the comparators
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 bits
CVREF = (CVR<4:0>/32)  (CVRSRC)
