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