Can the Digimesh modules do an IO change detection?

I have setup a xbee 802 module with change detect on D0. When I pull the input low the module send a message to the destination address as expected.

If I try the same setup with two Digimesh modules, no message is send when D0 change. I can send a message via the uart port which shows the network is setup correctly.

The question is if the Digimesh modules can do a change detect on their IO pins? If they can which is the important setup parameters I might be missing?

I think I found the solution. the 802 modules don’t need to be in API mode to do edge detection but the digi modules must be in API mode.
