Sorry for my late answer,

For Scott Wood :

That's the problem, I have no indication for use this function. What is the simple way of use it?

It's posible to use the window for this test?

Are there other registre to use (other ECM register)?

For Alexander YAKOVIEV :

I read this part and I wanted to know if we could use it after boot when we have in the main software?

Thanks

Guims

PS: sorry for my English

If you don't know what you need it for, what makes you think you need to do anything with it?  Normally it does its job without software interference.  The registers are mainly for error reporting.

OK,

I try to use it with SRIO

Thank you
