No, I'm only polling the regular status register. The Interrupt pins
are not connected. My application is single threaded anyway so polling
is fine for me - I would wait anyhow until the interrupt occured.

I once tried to switch to the alternate status register once completly,
but under some circumstances I'm getting not the expected data out of
it.
