PR (Pull-up/down Resistor Enable)
This command applies to the XBee Smart Modem.
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.
- If you set a PR bit to 1, it enables the pull-up/down resistor.
- 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.
