Memory Space Protection

0 0 0 0
To set up a transfer, the software specifies:
-
A
source port with an address that must hit in the source port memory
space.
-
A destination port with an address that must hit in the destination port
memory space.
If the software specifies a port with an address that does not hit this port
memory space (example: source port = EMIFF with an EMIFS start address
specified), the transfer continues and memory can be corrupted. No address
space check is performed by the DMA or outside the DMA.
It is the programmer's responsibility to ensure coherency between
the source port and source start address, and between the
destination port and destination start address.
