... Watchdog pulse and check its inputs to decide if it should resume normal operation or remain in sleep mode. The NCV8518B responds to the falling edge of the Watchdog signal, which it expects at least once during each Wakeup period. When the correct Watchdog signal is received, the Wakeup output is forced low. Other Watchdog pulses received within the same cycle are ignored ...
