Internal Pullup Enable for Port G Bits — Each of these control bits determines if the internal pullup device is
enabled for the associated PTG pin. For port G pins that are configured as outputs, these bits have no effect and
the internal pullup devices are disabled.
0 Internal pullup device disabled for port G bit n.
1 Internal pullup device enabled for port G bit n.
Output Slew Rate Control Enable for Port G Bits— Each of these control bits determine whether output slew
rate control is enabled for the associated PTG pin. For port G pins that are configured as inputs, these bits have
no effect.
0 Output slew rate control disabled for port G bit n.
1 Output slew rate control enabled for port G bit n.
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.
0 Low output drive enabled for port G bit n.
1 High output drive enabled for port G bit n.
