Is the interval timer implemented as a 16bit slave - requiring multiple operations to read the value?

If so you will have problems if the isr tries to access the timer at the same time as non-isr code.

I've NFI why Altera hasn't implemented 32bit versions of the timers, I'm sure they'd require less logic overall.
