Pullup Enable for Port C Bits — For port C pins that are inputs, these read/write control bits determine whether
internal pullup devices are enabled. For port C pins that are configured as outputs, these bits are ignored and
the internal pullup devices are disabled.
0 Internal pullup device disabled.
1 Internal pullup device enabled.
Slew Rate Control Enable for Port C Bits — For port C pins that are outputs, these read/write control bits
determine whether the slew rate controlled outputs are enabled. For port B pins that are configured as inputs,
these bits are ignored.
0 Slew rate control disabled.
1 Slew rate control enabled.
Data Direction for Port C Bits — These read/write bits control the direction of port C pins and what is read for
PTCD reads.
0 Input (output driver disabled) and reads return the pin value.
1 Output driver enabled for port C bit n and PTCD reads return the contents of PTCDn.
