[Example of setting transition conditions]
In this example, after an M7 code is decoded using the DEC
function instruction, control is passed to the next step.
NOTE
The TRSET function instruction is intended to
describe that a transition condition is satisfied. It is
used in a subprogram that is called from the
transition.
Beginning of selective branch
A branch occurs from one step to two or more steps, passing control to
a step below a transition where the condition is satisfied.
• A transition is placed below a branch.
• A step leading to the first transition where the transition
condition is satisfied becomes active.
• If transition conditions for more than one step are satisfied
simultaneously, transition occurs to the leftmost step.
• A branch can occur to up to 16 flows.
End of selective branches
Two or more flows that branched out gather back into one flow.
• The number of branching flows must match that of the gathering
flows.
