PIC18F2420/2520/4420/4520
REGISTER 19-2:
DS39631E-page 224
bit 7

2:
The POR value of the PCFG bits depends on the value of the PBADEN Configuration bit. When
PBADEN = 1, PCFG<2:0> = 000; when PBADEN = 0, PCFG<2:0> = 111.
AN5 through AN7 are available only on 40/44-pin devices.
Unimplemented: Read as ‘0’
VCFG1: Voltage Reference Configuration bit (V
1 = V
0 = V
VCFG0: Voltage Reference Configuration bit (V
1 = V
0 = V
PCFG<3:0>: A/D Port Configuration Control bits:
A = Analog input
