VRHEN: Voltage Reference High Enable bit (VRH = 4.096V nominal)
1 = Enabled, powers up reference generator
0 = Disabled, powers down reference generator if unused by LVD, BOR, or VRL
VRLEN: Voltage Reference Low Enable bit (VRL = 2.048V nominal)
1 = Enabled, powers up reference generator
0 = Disabled, powers down reference generator if unused by LVD, BOR, or VRH
VRHOEN: High Voltage Reference Output Enable bit
1 = Enabled, VRH analog reference is output on RA3 if enabled (VRHEN = 1)
0 = Disabled, analog reference is used internally only
VRLOEN: Low Voltage Reference Output Enable bit
1 = Enabled, VRL analog reference is output on RA2 if enabled (VRLEN = 1)
0 = Disabled, analog reference is used internally only
Unimplemented: Read as '0’
Legend:
R = Readable bit
