14.2.5 A/D port configuration register (ADPC)
This register switches the ANI0/P33 to ANI23/P105 pins to digital I/O of port or analog input.
When the comparator is in use, set the pins selected from among P81/ANI3/IVCMP00, P82/ANI4/IVCMP01,
P83/ANI5/IVCMP02, P84/ANI6/IVCMP03, and P85/ANI7/IVREF0 to analog input by using the ADPC register.
The ADPC register can be set by an 8-bit memory manipulation instruction.
Reset signal generation sets this register to 00H.
