DMA Read From an Unimplemented Address Space is not Reported as a BUS Error
AWR6443 ES2.0
The MSS DMA should generate a Bus Error (BER) interrupt when the DMA detects an error due to a read from an unimplemented address location. This interrupt is not available on any of the VIM Interrupt Channels for DMA1 and DMA2.
Implication: A DMA read from an unimplemented address can go undetected.
The DMA MPU has to be engaged with valid address range to ensure no occurrence of any read from an invalid address location happens.
DMA transfers have to be covered with end-to-end CRC from source to destination.
