End Of List. This opcode instructs the SBC that the end of the command block has been
encountered. Command processing stops and the interrupt is generated if the interrupt is enabled.
No command processing takes place (i.e., no 1553).
Skip. This opcode instructs the SBC to load the message-to-message timer with the value stored
in timer value location. The S IT will then wait the specified time before proceeding to the
next command block. This opcode allows for scheduling of specific time between message
execution. No command processing takes place (i.e., no 1553).
Go To. This opcode instructs the SBC to “go to” the command block as specified in the branch
address location. No command process takes place (i.e., no 1553).
Built-in Test. This opcode instructs the SBC to perform an internal built-in test. If the device passes
the built-in test, then processing of the next command block will continue. However if the device
fails the built-in test, then processing stops and an interrupt is generated, if the interrupt is enabled.
No command processing takes place (i.e., no 1553).
Execute Block; Continue. This opcode instructs the SBC to execute the current command block
and proceed to the next command block. This opcode allows for continuous operations.
Execute Block; Branch. This opcode instructs the SBC to execute the current command block and
unconditionally branch to the location as specified in the branch address location.
Execute Block; Branch on Condition. This opcode instructs the SBC to execute the current
command block and branch only if the condition is met. If no conditions are met, the opcode appears
as an execute and continue.
Retry on Condition. This opcode instructs the SBC to perform automatic retries, as specified in
the control word, if particular conditions occur. If no conditions are met, the opcode appears as an
execute and continue.
Retry on Condition; Branch. This opcode instructs the SBC to perform automatic retries, as
specified in the control word, if particular conditions occur. If the conditions are met, the SBC
retries. Once all retries have executed, the SBC branches to the location as specified in the branch
address location. If no conditions are met, the opcode appears as an execute and branch.
Retry on Condition; Branch if all Retries Fail. This opcode instructs the SBC to perform automatic
retries, as specified in the control word, if particular conditions occur. If the conditions are met and
all the retries fail, the SBC branches to the location as specified in the branch address location. If
no conditions are met, the opcode appears as an execute and continue.
Interrupt; Continue. This opcode instructs the SBC to interrupt and continue processing on the next
command block. No command processing takes place (i.e., no 1553).
Call. This opcode instructs the SBC to “go to” the command block as specified in the branch address
location without processing this block. The next command block address is saved in an internal
register so that the S IT may remember one address and return to the next command block.
No command processing takes place (i.e., no 1553).
Return to Call. This opcode instructs the SBC to return to the command block address saved during
the Call opcode. No command processing takes place (i.e., no 1553).
Reserved. The SBC will generate an illegal opcode interrupt (if interrupt enabled) and automatically
stop execution if a reserved opcode is used.
