10.0
This device contains an internal voltage regulator. To
provide a reference for the regulator, a band gap refer-
ence is provided. This band gap is also user accessible
via an A/D converter channel.
User level band gap functions are controlled by the
FVRCON register, which is shown in Register 10-1.

FIXED VOLTAGE REFERENCE
FVRRDY is always ‘1’ for the PIC16F72X devices.
Fixed Voltage Reference output cannot exceed V
FVRRDY
0 = Fixed Voltage Reference output is not active or stable
1 = Fixed Voltage Reference output is ready for use
FVREN
0 = Fixed Voltage Reference is disabled
1 = Fixed Voltage Reference is enabled
Unimplemented: Read as ‘0’
ADFVR<1:0>: A/D Converter Fixed Voltage Reference Selection bits
00 = A/D Converter Fixed Voltage Reference Peripheral output is off.
01 = A/D Converter Fixed Voltage Reference Peripheral output is 1x (1.024V)
10 = A/D Converter Fixed Voltage Reference Peripheral output is 2x (2.048V)
11 = A/D Converter Fixed Voltage Reference Peripheral output is 4x (4.096V)
