CANL is pulled to Vs. A signal transition at the wake pin WK from LOW to HIGH (rising
edge) causes a wake up and automatic transition into the cyclic HS ON mode (see
Figure 9). HS3 is activated again and also the long open window of the watchdog
mechanism. The watchdog has to be triggered correctly from that time on. If the signal
at the PWM pin makes a HIGH to LOW transition, the device switches to HS OFF again.
This wake up via the wake pin is comming from an external circuitry (switch, etc.) and
is not flagged by the RxD.
