Port D Pin Control Registers (PTDPE, PTDSE, PTDDS)
Internal Pullup Enable for Port D Bits — Each of these control bits determines if the internal pullup device is
enabled for the associated PTD pin. For port D 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 D bit n.
1 Internal pullup device enabled for port D bit n.
Output Slew Rate Control Enable for Port D Bits — Each of these control bits determine whether output slew
rate control is enabled for the associated PTD pin. For port D pins that are configured as inputs, these bits have
no effect.
0 Output slew rate control disabled for port D bit n.
1 Output slew rate control enabled for port D bit n.
