help
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.
if WDT_COUNTER
config WDT_COUNTER_CH_COUNT
int "Maximum number of supported channel"
default 4
range 1 255
help
Note that actual channel count will be limited to number of channels
supported by the counter device which is used for watchdog.
