The HI-6110 RT receives an RT to RT transfer with 2 data words
command from the MIL-STD-1553 bus. In this case, the HI-6110
is the receiving RT. The HI-6110 captures the message data and
issues the necessary Status Word. In this particular example, the
host did not update the Status Word Register and the HI-6110 re-
