5.6. Limitations on Stop Mode or Wait Mode
When using stop mode or wait mode, start the R8C UART debugger in free-run mode, and
close the RAM window, C watch window, and ASM window in advance. Also, do not operate
the R8C UART debugger until the program stops at the break point by setting the break
point after exiting stop mode or wait mode.
5.7. Watchdog Timer
The watchdog timer is refreshed while the monitor program is running. When using the
watchdog timer while running the user program, note that by referring to or changing
memory content, the monitor program intervenes and the watchdog timer is refreshed.
5.8. Real-time Operation of User Program
• Sampling run mode (also known as sampling mode)
In sampling mode, execution status of the user program will be regularly monitored when
executing Go and Come. Therefore, it is possible to detect when the user program is
stopped by a break or other command. Select this mode when performing normal
debugging.
• Free run Mode
In free-run mode, execution status of the user program will not be monitored when
executing Go and Come. Although real-time operation of the user program is secure, it is
not possible to detect if the user program is stopped by a break or other command.
Therefore, even when the user program stops, the R8C UART debugger does not stop
executing Go and Come. Press STOP to stop the R8C UART debugger.
Note: In free-run mode, use the R8C UART debugger while the RAM window, C watch
window, and ASM window are closed.
