PTKDS[7:0]
Output Drive Strength Selection for Port K Bits — Each of these control bits selects between low and high
output drive for the associated PTK pin. For port K pins that are configured as inputs, these bits have no effect.
0 Low output drive strength selected for port K bit n.
1 High output drive strength selected for port K bit n.
