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