● Program code between the SSTP instruction and the next SSTP instruction or the STPE
instruction is handled as a single process.
● These instructions make it easy to execute sequence control, selection branch control,
parallel branch merge control, and similar operations.
1) Sequence control
Only the necessary processes are switched and executed in order.
Process 1
2) Selective branch control
The processes are selected and executed according to conditions.
Process 1
3) Parallel branch/join control
