Debug with FXTH870902

I'm working with FXTH870902,and I encounter some questions :

No1:

The variables can not be preserved out of stop1 mode.

example:.

Var is a character variable;

Var equals to 5 in run mode,and then enter into stop1 mode.

if the system is on ACTIVE BACKGROUND DEBUG mode ,the Var will be preserved after wake up from stop1 mode.But in normal operation status, the Var will change after wake up from stop1 mode.

What to do? If I need that the Var will be preserved after wake up from stop1 mode when the system is on normal operation status

No2:

In stop1 mode, how to determine the vehicle is running？

Please help me

thanks
