Thanks, I will try this.

I will try to do a better description about what I wont realize, maybe It is an other way.

I have already a pic18f2550 connected with almost all pins, and a internal software with several function.
I need to read 2 or 3 more value, which one are coming from a pic16f876. This value are byte type.
I was thinking to connect all pic's in this way.
When I need the last value I will activate a pin from pic18f2550 like issue, and pic16f876 will respond with his value.
