Operation of XCALL instruction
When X0 is turned ON: Without process (Do not execute subroutine program of
"P1".)
During X0 is ON: Execute subroutine program of "P1".
When X0 is turned OFF: Perform "Non-execution processing" of subroutine
program of "P1".
Using SM734 (XCALL instruction executing condition designation) to select
operation when X0 is turned ON.
• When SM734 is OFF: Without process (Do not execute subroutine program of
"P1".)
• When SM734 is ON: Execute subroutine program of "P1".
During X0 is ON: Execute subroutine program of "P1".
When X0 is turned OFF: Perform "Non-execution processing" of subroutine
program of "P1".
When X0 is turned ON: Execute subroutine program of "P1".
During X0 is ON: Execute subroutine program of "P1".
When X0 is turned OFF: Perform "Non-execution processing" of subroutine
program of "P1".
