1 = Right justified. 6 Most Significant bits of ADRESH are read as ’0’.
0 = Left justified. 6 Least Significant bits of ADRESL are read as ’0’.
Unimplemented: Read as '0'
PCFG3:PCFG1: A/D Port Configuration Control bits
PCFG0: A/D Voltage Reference Select bit
1 = A/D reference is the V
0 = A/D reference is AV
Note: When this bit is set, ensure that the A/D voltage reference specifications are met.
