= AVSS
bit 4
VCFG0: Voltage Reference Configuration bit (VREF+ source)
1
= VREF+ (AN3)

bit 3-0
PCFG3:PCFG0: A/D Port Configuration Control bits
Legend:
R = Readable bit
W = Writable bit
U = Unimplemented bit, read as ‘0’
-n = Value at POR
‘1’ = Bit is set
‘0’ = Bit is cleared
x = Bit is unknown
A = Analog input
D = Digital I/O
Note 1: The POR value of the PCFG bits depends on the value of the PBADEN bit in
Configuration Register 3H. When PBADEN = 1, PCFG<3:0> = 0000;
when PBADEN = 0, PCFG<3:0> = 0111.
2: AN5 through AN7 are available only in PIC18F4X8X devices.
