DVP - ES2/SA2/SS2/SA2/SX2/SE Operation Manual - Programming

Program example 2:

1.When the rising-edge of X20 is triggered, CALL P10 instruction will transfer execution to subroutine P10.

2.When X21 is ON, execute CALL P11, jump to and run subroutine P11.

3.When X22 is ON, execute CALL P12, jump to and run subroutine P12.

4.When X23 is ON, execute CALL P13, jump to and run subroutine P13.

5.When X24 is ON, execute CALL P14, jump to and run subroutine P14. When the SRET instruction is reached, jump back to the last P subroutine to finish the remaining instructions.

6.The execution of subroutines will go backwards to the subroutine of upper level until SRET instruction in P10 subroutine is executed. After this program execution will return to the main program.
