SMBus device access

[Nils Faerber]

Oh, and while we are at it ;)
The PIC I have hanging to the SMBus not only has a display connectoed to
it but also some push buttons, i.e. user input.
It is not perfectly clear to me how I should best query those buttons.
Is it possible for the SMBus to generate interrupts on button presse or
do I have to poll those?
At least at first glance it seems that the SIS96x does not use
interrupts at all...

Thanks again!
