    Hi Denny,

    The memory protection unit can protect memory regions. It manage access to memory. The MPU allows ranges to be defined with different permissions and can read fault information. The MPU can also notify the system of a fault through an interrupt.

    It can restrict the access to the peripheral's configuration registers.

    For detailed description you can check the MPU user Guide: www.ti.com/.../sprugw5a.pdf.

    The MPU can manage ddr ranges. There is also a memory protection for the internal L1/L2 caches, see: www.ti.com/.../sprugw0c.pdf specifically Figure 1-1C66x CorePac Block Diagram.

    Best Regards,
    Yordan
