Core1553BBC MIL-STD-1553B Bus Controller
Bus Controller Operation
After power-up, the bus controller waits while the CPU
sets up the bus controller memory and registers. The
memory contains an instruction list, message blocks, and
data blocks. Once the instruction list, message blocks,
and data blocks are setup, the CPU starts the bus
controller. The bus controller works its way through all
the message blocks until it reaches the end of the
instruction list ( Figure 6 ).
Instruction
List
The instruction list contains a list of pointers to message
blocks. The message block contains the command words
transmitted on the 1553B bus and status words received
from the 1553B bus. It also contains a pointer to a data
block. The data block contains the data transmitted on
the 1553B bus, or the data received from the 1553B bus.

The instruction list contains pairs of words: an instruction
and a parameter. Core1553BBC supports a broad set of

with condition code support. This allows complex
instruction lists to be supported. The instruction contains
and Table 14 ).
All of the OPCODES support the condition code field. If
the condition is TRUE, then the OPCODE is carried out;
otherwise, the BC continues to the next instruction. For
RT-to-RT messages, the condition code will be true if the
bit is set in either status word or not set in either status
word ( Table 15 on page 14 ).
