6.10 Memory Protection Unit (MPU) Including IP Encapsulation
The FRAM can be protected by the MPU from inadvertent CPU execution and read or write access. 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 that can be configured in up to three segments in steps of 1KB.
- The access rights for each main and information memory segment can be individually selected.
- Access violation flags with interrupt capability for easy servicing of access violations.
