Question about DMA Memory Protection

Other Parts Discussed in Thread: TMS570LS3137

Hello Support,

In the TMS570LS3137 device, if I only enable DMA Memory Protection feature [No Cortex-R4 MPU feature enabled], then DMA Transactions to regions not defined by four available

DMAMPROE and DMAMPROS

registers are considered "NO DMA ACCESS ALLOWED [Error]" or "ANY DMA ACCESS ALLOWED [Pass]" condition by the Bus Matrix Module [BMM]?

Please help about DMA Memory Protection architecture related to NO ACCESS option of REGxAP bit fields [0x03 value].

Any information will be helpful for my understanding.

Thank you.

Regards

Pashan
