For all commands except RT to RT, the Command Word 1
registercontainsthelastvalidCommandWordreceived.
If the last valid command received was RT to RT, the
Command Word 1 register holds the first (receive) command
word and the Command Word 2 Register holds the second
(transmit) command word. Then if Message Register bits 3
and 9 are both 0, the Command Word 1 register contains the
validcommand.

If the last valid command received was RT to RT, the
Command Word 2 register contains the second (transmit)
command word. (See note above for Command Word 1.)
Whenever Message Register bit 3 or bit 9 is set, the valid
commandiscontainedintheCommandWord2register.
Whenever RCV is asserted, the active Command Word
register can always be determined by checking Message
Registerbits3and9.
status word transmitted by the remote terminal in response to
a (non-broadcast) command. Status word bits 15:11 are
automatically set to match the RT Address present at the
RTA4:0 input pins. The HI-6110 automatically transmits a
status word in response to valid non-broadcast commands.
The register may be changed anytime prior to status word
mid-sync bit.
The Transmit Status Word register is not
affectedbyMR,masterreset.
Received Status Word register captures the MIL-STD-1553
statuswordtransmittedbythereceivingremoteterminal.
The Receive Data FIFO is 32-words deep and holds MIL-
STD-1553datawordsreceivedbytheRT.TheFIFOiscleared
onMasterResetorafterallwordshavebeenreadbythehost.
Alow FFEMPTYflag (pin or Status register) means FIFO data
is available to be read by the host. Successive data reads
