If local shared RAM is configured as dedicated RAM for the CPU, or if it is configured as data RAM for the CLA, any fetch access from the CLA to that particular LSx RAM results in a CLA fetch protection violation, which is a non-controller access violation.
If a CLA fetch protection violation occurs, it results in a MSTOP. A flag gets set in the appropriate access violation flag register, and the memory address for which the access violation occurred, gets latched in the appropriate CLA fetch access violation address register. Also, an access violation interrupt is generated to the CPU if enabled in the interrupt enable register.
