How to break with debugger into a running program on ST8?

Dear experts,

Can anybody advice how to break into ST8 that started running without debugger connected?

In the Develop IDE I see only one option to start debugging, and it updates the program memory on the target. The target, I guess, will then reset/restart. How to avoid the restart?

Discuss with your tool vendor.

The tool vendor is STMicroelectronics... as it says in the 'About' dialog of the IDE...

Assuming for a second they aren't the only commercial tool vendor

 ,

Not sure if the STM8 has an inherent ability to support hot-plug or post-mortem debugging.

Consider adding your own diagnostic/monitor functions, ability to dump state when button, jumper or GPIO toggled.

Thank you. As I learn the ST chip and tools, I found ways to do without breaking in a running system.  Other toolkits are not an option for me unfortunately, the customer has chosen the STVD. 

Do you know perhaps, is inability to attach to running chip an inherent limitation of the hardware - ST8 or SWIM interface?
