ADFM: A/D Result Format Select bit
1 = Right justified. Six Most Significant bits of ADRESH are read as ‘0’.
0 = Left justified. Six Least Significant bits of ADRESL are read as ‘0’.
ADCS2: A/D Clock Divide by 2 Select bit
1 = A/D clock source is divided by two when system clock is used
0 = Disabled
VCFG1: Voltage Reference Configuration bit 1
0 = VREF- is connected to VSS
1 = VREF- is connected to external VREF- (RA2)
VCFG0: Voltage Reference Configuration bit 0
0 = VREF+ is connected to VDD
1 = VREF+ is connected to external VREF+ (RA3)

Legend: A = Analog input, D = Digital I/O
Note: AN5 through AN7 are only available on the 40-pin product variant (PIC16F747 and
PIC16F777).
Legend:
R = Readable bit
-n = Value at POR
W = Writable bit
‘1’ = Bit is set
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared x = Bit is unknown
