The bit field that configures the internal pull-up resistor status for the I/O lines.
-
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.
PR and PD only affect lines that are configured as digital inputs (3) or disabled (0).
The following table defines the bit-field map for PR and PD commands.
