Function
General Purpose Flag Bits 2-7.
These flags may be toggled, set or cleared when the BC logic
executes a FLG (General Purpose Flags Bits) op code, or
when the host writes the BC General Purpose Flag Register
0x0037.
No Response Flag.
This flag is set when an RT failed to respond to a command,
or responded later than the BC No Response Timeout
programmed using bits 15-14 in the BC Configuration Register
0x0032.
Format Error Flag.
This flag is set when the received response to the last
message had one or more violations to MIL-STD-1553B
validation criteria, including problems with sync, encoding, bit
count, parity, or word count.
This flag is also set when the received RT Status Word
response from the last message contained an incorrect RT
address field.
Good Data Block Transfer.
Reflecting status for the last 1553 message, this flag is set
after completion of error-free RT-to-BC transfers, RT-to-RT
transfers, or transmit mode code commands with data. This
flag is reset after invalid messages, or after completion of BC-
to-RT transfers, receive mode code commands with data, or
mode code commands without data. This flag may be used to
determine when the transmit aspect of an RT-to-RT transfer is
error-free.
Masked Status Set.
Reflecting status for the last 1553 message, this flag is set
when one or both of the following conditions occurred:
•
•
52
In the message BC Control Word, at least one of the Sta-
tus Mask bits 14-9 are logic 0, but the corresponding bit
or bits are set in the received RT Status Word. When the
Reserved Bits Mask (message BC Control Word bit 9) is
logic 0, this flag is set when any or all of the three reserved
bits are set in the received RT Status Word.
In the BC Configuration Register 0x0032, the BCR (broad-
cast command received) Mask Enable bit 0 is logic 1. the
Mask Broadcast bit 5 in the message BC Control Word is
logic 0, and the BCR (Broadcast Command Received) bit
4 is logic 1 in the received RT Status Word.
