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

Pull-down devices only apply when using pin interrupt functions, when
corresponding edge select and pin select functions are configured.
