CANL is pulled to Vs. After the transition from HS ON to HS OFF, an autotiming function
is started. This is a timer controled by the internal oscillator, which can be programed by
SPI IBit 12,13. If the timer exceeds the programed time this causes a wake up and
automatic transition into the cyclic HS ON mode (see Figure 10). 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 autotiming function is not flagged to the µC by setting the RxD pin.

open window is max. 20 cycles
long open window is max. 128 cycles
otherwise
a watchdog reset will be generated
