Internal Pull Enable for Port K Bits — Each of these control bits determines if the internal pull-up device is
enabled for the associated PTK pin. For port K pins that are configured as outputs, these bits have no effect and
the internal pull devices are disabled.
0 Internal pull-up device disabled for port K bit n.
1 Internal pull-up device enabled for port K bit n.
Output Slew Rate Enable for Port K Bits — Each of these control bits determines if the output slew rate control
is enabled for the associated PTK pin. For port K pins that are configured as inputs, these bits have no effect.
0 Output slew rate control disabled for port K bit n.
1 Output slew rate control enabled for port K bit n.
