6.12 Memory Protection Units

The MPU performs memory protection checking. It receives requests from a bus master in the system and checks the address against the fixed and programmable regions to see if the access is allowed. If allowed, the transfer is passed unmodified to its output bus (to the targeted address). If the transfer is illegal (fails the protection check) then the MPU does not pass the transfer to the output bus but rather services the transfer internally back to the input bus (to prevent a hang) returning the fault status to the requestor as well as generating an interrupt about the fault. The following features are supported by the MPU:

  • Provides memory protection for fixed and programmable address ranges
  • Supports multiple programmable address region
  • Supports secure and debug access privileges
  • Supports read, write, and execute access privileges
  • Supports privid(8) associations with ranges
  • Generates an interrupt when there is a protection violation, and saves violating transfer parameters
  • MMR access is also protected
