Hi Jan, Datasheet talks about DMA :
"The DM9000 provides DMA capability to simplify the access of the internal memory. After the programming of the starting address of the internal memory and then issuing a dummy read/write command to load the current data to internal data buffer, the desired location of the internal memory can be accessed by the read/write command registers. The memory’s address will be increased with the size that equals to the current operation mode (i.e. the 8-bit, 16-bit or 32-bit mode) and the data of the next location will be loaded into internal data buffer automatically. It is noted that the data of the first access (the dummy read/write command) in a sequential burst should be ignored because that the data was the contents of the last read/write command." I will try to contact the contact the technical support for more information. Regards, WALLOIS Cyril
