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