Port Configuration Register (PCON).
The PCON config-
ures the ports individually for comparator output on Port 3.
The PCON Register is located in the Expanded Register
File at Bank F, location 00 (Figure 13).
Bit 0 multiplexes comparator AN1 Output at P34. A "1" in
this location brings the comparator output to P34
(Figure 14), and a "0" puts P34 into its standard I/O config-
uration.
Note:
Only comparator output AN1 is multiplexed to a
Port 3 output. Comparator AN2 output is not connected to
any pins. Note that the PCON Register is reset upon the
occurrence of a WDT RESET (not in STOP Mode), and
Power-On Reset (POR).
