VI_ATTR_TRIG_DIR is a bit map of the directions of the mapped TTL trigger lines. Bits 0-7 represent TTL triggers 0-7 respectively. A bit's value of 0 means the line is routed out of the frame, and a value of 1 means into the frame. In order for a direction to be set, the line must also be enabled using VI_ATTR_VXI_TRIG_LINES_EN.
