Hi all,
I am trying to interface a C6747 Spectrum Digital EVM to our daughter board with an ADC. The ADC feeds data to a SN74V215 FIFO which I am then trying to read via the EMIFA. It mostly works but I am getting bit errors. I suspect that the problem is the way that I have the FIFO configured to the EMIFA. Right now I have:
FIFO /OE = EMIFA /CS + EMIFA /OE
FIFO RCLK = EMIFA /CS + EMIFA /OE
FIFO /REN = GND (i.e. reads always enabled)
I've tried following the information in spra543.pdf about interfacing an asynchronous EMIF to a FWFT synchronous FIFO but the C6747 doesn't seem to have the /RE signal that is available for the older DSPs (spra543 discusses C6201/C6701). Does anyone know how to do this for a C6747?
Thanks,
Lori
