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