Status Set.
This bit is not affected by the values of mask bits 14-9 in the BC Control
Word for the message.
This bit is logic 1 when the received RT Status Word contains an
unexpected bit value in the bit 10-0 range. The expected value is usually
logic 0 for bits 10-0 in the received RT Status Word.
Exception: the expected value for Broadcast Command Received bit 4 in
the received RT Status Word is logic 1 when BCRME bit 0 is logic 1 in the
BC Configuration Register 0x0032, and MASKBCR bit in the BC Control
Word bit is logic 0
Format Error.
This bit is logic 1 when a received RT response violates MIL-STD-1553
message validation criteria. This includes sync, word count, encoding, bit
count or parity errors. Word bits 2-0 provide additional information. This
flag is also set when the received RT Status Word response from the last
message contained an incorrect RT address field.
No Response Timeout Error.
This bit is logic 1 when an RT fails to respond, or responds later than
the BC No Response Timeout interval specified by bits 15-14 in the BC
Configuration Register 0x0032.
Loopback Error.
The HI-613x BC evaluates its own 1553 message transmissions. The
received version of each word transmitted by the BC is checked for 1553
validity (sync, encoding, bit count and/or parity error). In addition, for each
message transacted, the received image for the last word transmitted by
the BC is evaluated for data match.
This bit is logic 1 when the received version for one or more words
transmitted by the BC fails 1553 “word validity” criteria, and/or the
received version for the last word transmitted by the BC does not match
the Manchester II word transmitted by the BC.
Masked Status Set.
This bit is logic 1 when any of the following conditions occurs:

•
HI-6130, HI-6131
One or more of the mask bits 14-9 in the BC Control Word is logic 0
and the corresponding bit is logic 1 in the received RT Status Word.
Or the BCRME bit 0 is logic 1 in the BC Configuration Register 0x0032
and the MASKBCR bit in the BC Control Word is logic 0 and the
Broadcast Command Received bit 4 is logic 1 in the RT Status Word.
Or the BCRME bit 0 is logic 0 in the BC Configuration Register
0x0032 and the MASKBCR bit in the BC Control Word differs from
the Broadcast Command Received bit 4 in the RT Status Word.
Or the received RT Status Word contains an RT Address field different
from the RT Address field in the transmitted Command Word.
