I was reading the specs on Robostix, and am a bit confused about how many inputs can actually be used as interrupts. Can the entire "Interrupts" group be, in fact, used as interrupts, as the name would indicate, or are there only certain inputs that can be, as is implied in the table describing inputs for this group? Sorry if there's an obvious answer here that I'm not seeing, but this seemed a little ambiguous to me.
Also, what's the maximum rate that one of the interrupts could count at, assuming all the code's doing is incrementing a variable?
Thanks a lot
