2.4.1.2. MPU Address Space

The MPU address space is 4 GB and applies to addresses generated inside the MPU.

The MPU address space contains the following regions:
  • The SDRAM window region provides access to a large, configurable portion of the 4 GB SDRAM address space.

The address filtering start and end registers in the L2 cache controller define the SDRAM window boundaries. The boundaries are megabyte-aligned. Addresses within the boundaries route to the SDRAM master. Addresses outside the boundaries route to the system interconnect master.
