Using the Start/Stop Function
The emulator executes the specified routine of the user program immediately before starting and immediately after halting
program execution. This function is used to control the user system in synchronization with execution and halting of the user
program.
5.15.1 Opening the Start/Stop Function Setting Dialog Box
The routine executed immediately before starting and immediately after halting the user program execution is specified in the
[Start/Stop function setting] dialog box.
To open the Start/Stop function setting dialog box, choose Setup -> Emulator -> Start/Stop function setting… from the menu.

5.15.2 Specifying the Routine to be executed
It is possible to specify the respective routines immediately before starting and immediately after halting the user program
execution.
When The specified routine is executed immediately before execution of the user’s program check box is selected, the routine
specified in the Starting address combo box, which is below this check box, is executed immediately before starting user
program execution.
When The specified routine is executed immediately after the stop of the user’s program check box is selected, the routine
specified in Starting address combo box, which is below this check box, is executed immediately after halting user program
execution.
5.15.3 Limitations of the Start/Stop Function
The Start/Stop function is subject to the following limitations.
- While the Start/Stop function is in use, do not use the debug functions listed below.

5.15.3 Limitations of the Start/Stop Function
The Start/Stop function is subject to the following limitations.
- While the Start/Stop function is in use, do not use the debug functions listed below.
(a) Memory setting and download into the program area of a specified routine
(b) Breakpoint setting in the program area of a specified routine
(b) Breakpoint setting in the program area of a specified routine
- While a specified routine is executed, the 4-byte value pointed to by the interrupt stack is used under control on the emulator
side.
- The general-purpose registers and flags used in a specified routine are subject to the following limitations.
