Core1553BBC MIL-STD-1553B Bus Controller
Message Block
An 8-word message block controls each message. The BC reads the 1553B command words from the message block
and will write the received status words back to message block. Message blocks must be positioned on an 8-word
memory boundary ( Table 16 ).

Type of 1553B Message
Inter-message GAP (IMG) after this message, 0 to 63 μ s.
15:10
When 000000, it uses the inter-message gap as set by the BC setup register.
Longer IMG values can be achieved by using the DELAY instruction between
messages.
The actual IMG may be llonger than when set by this register. The BC needs
to perform up to six memory accesses during the IMG period. If the backend
memory responds slowly, then the IMG may increase
