Port T 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.
