Port S pull device enable—Enable pull devices on input pins
These bits configure whether a pull device is activated, if the associated pin is used as an input. This bit has no effect
if the pin is used as an output. Out of reset all pull devices are enabled.
1 Pull device enabled.
0 Pull device disabled.
Port S pull device select—Determine pull device polarity on input pins
This register selects whether a pull-down or a pull-up device is connected to the pin.
1 A pull-down device is connected to the associated pin, if enabled and if the pin is used as input.
0 A pull-up device is connected to the associated pin, if enabled and if the pin is used as input.
