Hello NPVV,
I found a
Knowledgebase by searching "change detection 6210" from our
homepage that states, no, your device does not support that property. Most of our M series devices do, however the bus powered devices do not. If you only need to detect changes in one line, then you could try to use two retriggerable generate digital pulse counter tasks (one for rising edge, one for falling) to output a pulse on the edges, then somehow combine the outputs of the two counters into one sample clock. Other than this, I do not know of a good way to work around this issue. If you figure something out, it would be great if you could post it.
