Supports a default global entry for memory space not covered by other regions:
— Default access protection
— Default guarded attribute
Interrupt generated upon:
— Access violation
— Load from guarded region
— Write to read-only region
The MSR[DR] bit (data relocate) controls DMPU protection on/off operation
Programming is done using the mtspr/mfspr instructions to/from implementation-specific special
purpose registers.
No protection for accesses to the CALRAM module on the L-bus (CALRAM has its own
protection options)
L2U Block Diagram
– Access protection: user or supervisor
– Guarded attribute: speculative or non-speculative
– Enable/disable option
– Read only option
