NI 9403 Direction Control

The direction control field has one bit for each I/O pin, with bit 0 matching

channel 0, and so forth. 0 in the direction control indicates that I/O is an

input; 1 indicates an output.

Note Both the input and output data is transmitted in the PDO regardless of the direction

control; only the relevant bits are connected to the I/O pins.
