PIN FUNCTIONS (Continued)

Port Configuration Register (PCON). The PCON con-

figures 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

configuration.

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).
