Port Configuration Register
The Port Configuration (PCON) register (see
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 comparator
outputs to P34 and P37, and a 0 releases the Port to its standard I/O configuration.
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.
Stop Mode Recovery Register (SMR)
This register selects the clock divide value and determines the mode of Stop Mode
Recovery (see
flag bit that is hardware set on the condition of Stop recovery and reset by a power-on
