6.9 Memory Protection Unit Including IP Encapsulation
The FRAM can be protected from inadvertent CPU execution, read access, or write access by the MPU. Features of the MPU include:
- IP encapsulation with programmable boundaries in steps of 1KB (prevents reads from "outside"; for example, JTAG or non-IP software).
- Main memory partitioning is programmable up to three segments in steps of 1KB.
- Each segment's access rights can be individually selected (main and information memory).
- Access violation flags with interrupt capability for easy servicing of access violations.
