Port Configuration Register (PCON)
The PCON register (Figure 33) configures the comparator output on Port 3. It is
located in the expanded register 2 at Bank F, location 00.

Comparator Output Port 3 (D0)
Bit 0 controls the comparator used in Port 3. A 1 in this location brings the compar-
ator outputs to P34 and P37, and a 0 releases the 0ort to its standard I/O configu-
ration.
Port 1 Output Mode (D1)
Bit 1 controls the output mode of port 1. A 1 in this location sets the output to
push-pull, and a 0 sets the output to open-drain.
Port 0 Output Mode (D2)
Bit 2 controls the output mode of port 0. A 1 in this location sets the output to
push-pull, and a 0 sets the output to open-drain.
