C1VREN: Comparator 1 Voltage Reference Enable bit
1 = CVREF circuit powered on and routed to C1VREF input of Comparator C1
0 = 0.6 Volt constant reference routed to C1VREF input of Comparator C1
C2VREN: Comparator 2 Voltage Reference Enable bit
1 = CVREF circuit powered on and routed to C2VREF input of Comparator C2
0 = 0.6 Volt constant reference routed to C2VREF input of Comparator C2
VRR: CVREF Range Selection bit
1 = Low range
0 = High range
FVREN: Fixed Voltage Reference (0.6V) Enable bit
1 = Enabled
0 = Disabled
VR<3:0>: Comparator Voltage Reference CVREF Value Selection bits (0 ≤ VR<3:0> ≤ 15)
When VRR = 1: CVREF = (VR<3:0>/24) * VDD
When VRR = 0: CVREF = VDD/4 + (VR<3:0>/32) * VDD
