EMAFE daughter card interface programming problem in EZ-LIT Lite 21065L evaluation kit

Hi All,

         I am using ADSP21065L EZ-KIT Lite evaulation system and want to connect my daughter card via the EMAFE expansion connector. The system memory map provides EMAFE address location at 0x01000000 and EMAFE data location at 0x01000001 in external block 0 memory space. My daughter card will have a programmable address and DSP is supposed to read a fixed no. of bytes(using multiple read cycles) after geenrating particular address and WR/CS signals.

I couldn't find any sample code in the example programs explaining the sequence of putting address/data and control signals to perform read/write operation via EMAFE port. Could someone help me how to program the EMAFE interface properly to perform the desired operation.


Best Regards,

Adeel Malik
