Output Drive Strength Selection for Port F Bits — Each of these control bits selects between low and high
output drive for the associated PTF pin. For port F pins that are congured as inputs, these bits have no effect.
0 Low output drive strength selected for port F bit n.
1 High output drive strength selected for port F bit n.
