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

Unimplemented: Read as ‘0’

VCFG1: Voltage Reference Configuration bit (VREF- source)

1 = VREF- (AN2)

0 = AVSS

VCFG0: Voltage Reference Configuration bit (VREF+ source)

1 = VREF+ (AN3)

0 = AVDD

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 on PIC18F4682/4685 devices.
