Hello !

 

I can see that amount of used MPU regions has effect to power consumption:

"

Disabling the MPU by clearing CESR[VLD] minimizes power dissipation. To minimize
the power dissipation of an enabled MPU, invalidate unused region descriptors by
clearing the associated RGDn_Word3[VLD] bits.

"

 

How large effect for power consumption are ?

Does this valid for RUN mode or even in LLS3 mode can be some effect ?

 

Regards,

Eugene
