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
Hi Eugene,
1. When MPU work, it has power consumption. But there is no such day. I think it is according to how it access the protected area.
2. MPU module needn't clock. When XBS stop, it also stop. It will not dissipate power in low power stop mode.
