Hi all,

Thanks for you answers.
You were right Alan, I've defined T2 as a sfr16 in order to use the 16 bits value in a variable.

But I didn't seen that T2 was already defined as sbit !!! So Stupid ...

Now it's working as well as I was expecting.

For information, I've wrote a regular runtime executive sequencer to manage the tasks of the microcontroller including a processor load monitoring and it's working very fine.

I'll put all my routines on a website in a few weeks....
