What we did to check this is to wire 8 digital inputs together to a momentary switch. We then modified our 2002 software to output the values of the switches using debug. Just manually flicking the switch by hand rapidly will result in one sample every few seconds that isn't 0xFF or 0x00, but is a random bit pattern.

Interesting. I guess this means there is no point to using both. Oh well, that just means more available digital inputs!
