Data Sheet Clarifications
The following typographic corrections and clarifications
are to be noted for the latest version of the device data
sheet (DS41579C):
1. Module: Correction to ADCON1 Register
The following correction applies to Register 17-2:
ADCON1 A/D Control Register in the device data
sheet.
REGISTER 17-2: ADCON1: A/D CONTROL REGISTER 1
Note: Corrections are shown in bold. Where
possible, the original bold text formatting
has been removed for clarity.

ADFM ADCS<2:0> — ADNREF ADPREF<1:0>
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
bit 7 ADFM: A/D Result Format Select bit (see Figure 17-3)
1 = 2’s complement format.
0 = Sign-magnitude result format.

bit 3 Unimplemented: Read as ‘0’
bit 2 ADNREF: A/D Negative Voltage Reference Configuration bit
1 =VREF- is connected to external VREF- pin
(1)
0 =VREF- is connected to VSS
bit 1-0 ADPREF<1:0>: A/D Positive Voltage Reference Configuration bits
11 =V
REF+ is connected internally to FVR Buffer 1
10 = Reserved
01 =V
REF+ is connected to VREF1+ pin
00 =V
REF+ is connected to VDD
Note 1: When selecting the FVR or VREF1+ pin as the source of the positive reference, be aware that a minimum
voltage specification exists. See Section 30.0 “Electrical Specifications” for details.
