APPSS Cortex-M4F doesn't get the correct error response when cluster 3 retention memories are accessed in low-power deep-sleep powered down state

Revision(s) Affected

IWRL6432 ES1.0

Details

The logic to generate error when Cortex-M4F tries to access cluster 3 memories in powered down state is incorrect due to which Cortex-M4F doesn't get the correct error response.

Workaround

Software shouldn't try to access cluster 3 retention memories during low-power deep-sleep powered down state

This has been fixed in ES2.0.
