Self-Test Message Off-Line.
If this Control Word bit is logic 1, transmission of this message onto the
1553 bus is inhibited. Instead the digitally-encoded Command Word is
looped back into the receive decoder for the selected bus. This tests both
the encoding and decoding signal paths. Upon message completion, Loop
Test Fail bit 8 in the Block Status Word indicates the self-test result.
If BC is configured for 16-bit time base, the received Loopback Word is
stored in the Message Control/Status Block. If the BC is configured for 32-
bit time base, time tag bits 31-16 are stored in the Loopback Word location.
Mask Broadcast Command Received Bit.
If the BCRME bit 0 is logic 1 in the BC Configuration Register 0x0032,
then this Control Word bit is a “mask bit” like bits 14-9, acting upon the BCR
Broadcast Command Received bit 4 in the received RT Status Word:
If the BCRME bit 0 is logic 0 in the BC Configuration Register 0x0032,
then this MASKBCR Control Word bit reflects the expected state of the
Broadcast Command Received bit 4 in the received RT Status Word:
See Table 7.
End of Message Interrupt.
If the BCEOM bit 3 is logic 1 in the BC Interrupt Enable Register 0x0010, an
EOM interrupt will occur upon message completion, if this Control Word bit
is logic 1.
This bit is not used.

HOLT INTEGRATED CIRCUITS
If this MASKBCR Control Word bit is logic 0 and the Broadcast
Command Received bit 4 is logic 1 in the received RT Status Word, a
“Status Set” condition will result.
If this MASKBCR Control Word bit is logic 1, the Broadcast Command
Received bit 4 in the received RT Status Word has no effect on the
outcome for a “Status Set” condition.
If this MASKBCR Control Word bit does not match the logic state
of the Broadcast Command Received bit 4 in the received RT Status
Word, a “Status Set” condition will result.
If this MASKBCR Control Word bit matches the logic state of the
Broadcast Command Received bit 4 in the received RT Status Word,
then the Broadcast Command Received bit 4 in the received RT Status
Word has no effect on the outcome for a “Status Set” condition.
