2:
The Reset value of the PCFG bits depends on the value of the PBADEN Configuration bit. When
PBADEN = 1, PCFG<3:0> = 0000; when PBADEN = 0, PCFG<3:0> = 0111.
AN5 through AN7 are available only on 40-pin and 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
