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.
