Port C Data Direction—
This register controls the data direction of pins 7 through 0.
The external bus function controls the data direction for the associated pins. In this case the data direction bits will
not change.
When operating a pin as a general purpose I/O, the associated data direction bit determines whether it is an input
or output.
1 Associated pin is configured as output.
0 Associated pin is configured as high-impedance input.
Port D Data Direction—
This register controls the data direction of pins 7 through 0.
When used with the external bus this function controls the data direction for the associated pins. In this case the data
direction bits will not change.
When operating a pin as a general purpose I/O, the associated data direction bit determines whether it is an input
or output.
1 Associated pin is configured as output.
0 Associated pin is configured as high-impedance input.
