Disable cryptocell hardware to save power

[jonas.woerner]

Hi,

currently I am trying to figure out how to disable the cryptocell hardware after enabling it, because if I enable it and then enter systemOFF, the system still draws about 35uA.

I enable it with:

NRF_CRYPTOCELL->ENABLE = 1;

then the system draws about 800uA of power.

then I do

NRF_CRYPTOCELL->ENABLE = 0;

and enter systemOFF, but I still draw some current.

If I dont enable it prior, my current goes down below 1uA.

so How do I completly disable the cryptocell processor?

thanks,

Jonas

Hi Jonas

Seeing as this is a more general issue than first anticipated, I will continue this over on the new post you created, and will be closing this one to avoid confusion.

Best regards,

Simon
