Timer0 wake-up event

yoniw

Hi Biser,

Is Timer0 event can be used as a wake-up source from Deepsleep0 state?

Although I don't see Timer0 as a wakeup source in TRM 8.1.4.5 list ,

I do see that per TRM table 20-2 its power domain is wakeup domain which remain on during deepsleep0

Hi,

Timer0 is in the wakeup domain and ideally timer0 events can be used as wakeup source for DS0.

However, it is a secure timer and hence Timer1 is usually used for the purpose.

Regards

Sandhya
