Watchdog emulated with counter device. If counter device supports using
|
|
zero latency interrupts (ZLI) then expiration callback can be called from
|
|
that context. This watchdog can be used along hardware watchdog to
|
|
overcome hardware watchdog limitations, e.g. Nordic devices reset
|
|
unconditionally at fixed time after hitting watchdog interrupt, leaving
|
|
no time to print debug information. Watchdog has limitations since it
|
|
cannot interrupt same or higher priorities so it cannot fully replace
|
|
hardware based watchdog.

Note that actual channel count will be limited to number of channels
|

supported by the counter device which is used for watchdog.
