• Manufacturer: MICROCHIP [Microchip Technology]

PIC18F2682/2685/4682/4685
REGISTER 19-2:
DS39761B-page 248

2:
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.
AN5 through AN7 are available only on PIC18F4682/4685 devices.
Unimplemented: Read as ‘0’
VCFG1: Voltage Reference Configuration bit (V
1 = V
0 = AV
VCFG0: Voltage Reference Configuration bit (V
1 = V
0 = AV
