Sorry....
fire-off means call ADCy.getData();
This will start the second (Y) conversion.
Then in ADCy.dataReady() call ADCz.getData();
to start the Z conversion. In ADCz.dataReady()
you could chain back to ADCx.getData() or leave
it to your timer to start the next set.

I found no method to fire off.
I use tmote sky
