Continued Sleep - Wakeup cycle with MC33771C

Is it possible to keep the MC33771C in a continuous sleep / wakeup cycle unless an error occurred?

I can see that it sleeps for the selected timed (e.g. 8sec) and then it wakes up for measurement cycle.

Even if all wakeup masks are set (to disable)  there is a wakeup pulse (TPL) to the MC33664.

Is there a way to keep the MC33771C in a cyclic loop without MCU interaction?
