1.4 Mode Code and Subaddress
The UT1760A RTS provides two modes of illegal
subaddress decoding, one meeting MIL-STD-1760A
Notices I and II, and the other meeting MIL-STD-1760A
Notice III. In addition, the device has automatic internal
illegal command decoding for reserved MIL-STD-1553B
mode codes. These definitions are extracted from MIL-
STD-1760A and reviewed in section 1.5 of this document.
Upon command word validation and decode, status pins
MCSA(4:0) and MC/SA become valid. Status pin MC/SA
will indicate whether the data on pins MCSA(4:0) is mode
code or subaddress information. Status Register bits 0
through 5 contain the same information as pins MCSA(4:0)
and MC/SA. The system designer can use signals
MCSA(4:0), MC/SA, BRDCST, RTRT, etc. to illegalize
mode codes, subaddresses, and other message formats
(broadcast and RT-to-RT) via the Illegal Command
(ILLCOM) input to the part.
