Pull-highResistors
Many product applications require pull-high resistors for their switch inputs usually requiring the use
of an external resistor. To eliminate the need for these external resistors, all I/O pins, when configured
as an input have the capability of being connected to an internal pull-high resistor. These pull-high
resistors are selected using registers PAPU~PDPU and are implemented using weak PMOS
transistors.
