| 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. |
