The HI-6110 RT receives a Mode Command with Data word
(Receive) from the MIL-STD-1553 bus. The correct Status Word
is returned and the host reads the Mode Data value. In this
particular example, the host reads the Message Register to
determine what type of MIL-STD-1553 command was received. A
default value is used for the Status Word response.
The HI-6110 RT receives a Broadcast RT to RT transfer
Command with 2 data words from the MIL-STD-1553 bus. The
HI-6110 RT is the transmitter. Note that RCVA/B doesn’t go high
until the Transmit Command matching the HI-6110 RT address is
received. The HI-6110 broadcasts the message and does not wait
for a Status Word to be returned.
