Data Sheet Clarifications
The following typographic corrections and clarifications
are to be noted for the latest version of the device data
sheet (DS41391D):
1. Module: Temperature Indicator
In Register 14-1: FVRCON: Fixed Voltage
Reference Control Register, the TSEN and
TSRNG bits that enable and select the range for
the temperature indicator module are missing. The
corrected register table is shown below.
REGISTER 14-1: FVRCON: FIXED VOLTAGE REFERENCE CONTROL REGISTER
Note: Corrections are shown in bold. Where
possible, the original bold text formatting
has been removed for clarity.

bit 7 bit 0
Legend:
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
u = Bit is unchanged x = Bit is unknown -n/n = Value at POR and BOR/Value at all other Resets
‘1’ = Bit is set ‘0’ = Bit is cleared q = Value depends on condition
bit 7 FVREN: Fixed Voltage Reference Enable bit
0 = Fixed Voltage Reference is disabled
1 = Fixed Voltage Reference is enabled
bit 6 FVRRDY: Fixed Voltage Reference Ready Flag bit
(1)
0 = Fixed Voltage Reference output is not ready or not enabled
1 = Fixed Voltage Reference output is ready for use
bit 5 TSEN: Temperature Indicator Enable bit
(3)
0 = Temperature Indicator is disabled
1 = Temperature Indicator is enabled
bit 4 TSRNG: Temperature Indicator Range Selection bit
(3)
0 =VOUT = VDD - 2VT (Low Range)
1 =V
OUT = VDD - 4VT (High Range)
bit 3-2 CDAFVR<1:0>: Comparator and DAC Fixed Voltage Reference Selection bit
00 = Comparator and DAC Fixed Voltage Reference Peripheral output is off.
01 = Comparator and DAC Fixed Voltage Reference Peripheral output is 1x (1.024V)
10 = Comparator and DAC Fixed Voltage Reference Peripheral output is 2x (2.048V)
(2)
11 = Comparator and DAC Fixed Voltage Reference Peripheral output is 4x (4.096V)
(2)
bit 1-0 ADFVR<1:0>: ADC Fixed Voltage Reference Selection bit
00 = ADC Fixed Voltage Reference Peripheral output is off.
01 = ADC Fixed Voltage Reference Peripheral output is 1x (1.024V)
10 = ADC Fixed Voltage Reference Peripheral output is 2x (2.048V)
(2)
11 = ADC Fixed Voltage Reference Peripheral output is 4x (4.096V)

Note 1: FVRRDY is always ‘1’ on devices with LDO (PIC16F1826/27).
2: Fixed Voltage Reference output cannot exceed V
DD.
