Explanations:
SRET indicates the end of subroutine program. The subroutine will return to main program and
begin execution with the instruction after the CALL instruction.
Program example 1:
When X0 = ON, the CALL instruction will jump to P2 and run the subroutine. With the execution of
the SRET instruction, it will jump back to address 24 and continue the execution.

Program example 2:
1. When the rising-edge of X20 is triggered, CALL P10 instruction will transfer execution to
subroutine P10.
2. When X11 is ON, execute CALL P11, jump to and run subroutine P11.
3. When X12 is ON, execute CALL P12, jump to and run subroutine P12.
4. When X13 is ON, execute CALL P13, jump to and run subroutine P13.
5. When X14 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.
