See PR (Pull-up/down Resistor Enable) for bit mappings, which are the same.
Parameter range
0x0 – 0x7FFF
Default
0 – 0x7FFF
PR (Pull-up/down Resistor Enable)
Sets or displays the bit field that configures the internal resistor status for the digital input lines.
Internal pull-up/down resistors are not available for digital output pins, analog input pins, or for
disabled pins.
Use the PD command to specify whether the resistor is pull-up or pull-down.
n If you set a PR bit to 1, it enables the pull-up/down resistor.
n If you set a PR bit to 0, it specifies no internal pull-up/down resistor.
The following table defines the bit-field map for both the PR and PD commands.
