3.7.7.7. Supervisor-Only Data Address

When your system contains an MMU and the processor is in user mode (status.U = 1), any attempt to access a supervisor-only data address results in a supervisor-only data address exception. Instructions that can cause a supervisor-only data address exception are all loads, all stores, and flushda.

This exception is implemented only in Nios® II processors that include the MMU.
