I have an SMSC Ethernet controller connected to BF548 via async bus. I'm interested to transfer the Ethernet frames from async bus to another BF548 processor via EPPI0(16 data lines) interface. In order to achieve a maximum data transfer throughput over PPI interface, what mode I should configure? Ethernet frames vary in size 64 to 1518 bytes how to handle this situation ..? . Kindly help.
