Use the min_heartbeat value instead of the calculated heartbeat value for the first watchdog reset to avoid spurious watchdog reset. Resetting the watchdog counter during init might lead to a watchdog fault reset because the watchdog counter has to be running for at least min_heartbeat. Resetting the watchdog counter after heartbeat might lead to a watchdog timeout reset because the watchdog counter is running for more than max_heartbeat time. Using min_heartbeat instead of heartbeat does not guarantee that the watchdog won't trigger a reset, but at least it reduces the chances to be in such a case.
