According to the documentation, there are two modes for the ATTN pin:

- `arm` mode which can be manually triggered remotely by adding a note to an inbound `.qi` file. This mode pulls the ATTN pin LOW, and then briefly HIGH when a change to the note file(s) is/are detected.
- `watchdog` mode which is sort of the opposite of `arm` mode. ATTN pin is pulled HIGH, but briefly LOW if no requests are made to the Notecard for x seconds.

Is it possible to implement a watchdog-like mode for the ATTN pin which is _manually_ triggered like with `arm` mode (without extra hardware)? Basically, I’d like to be able to force reset my device if necessary in the field, and not necessarily rely on the `watchdog` mode.
