SHARC ADSP-21375

Started by rkn80 November 28, 2008
HI,

I'm using the ADSP-21375 SHARC.
Does anybody know how I can write data to external data bus without
using the AMI or the SDRAM controller?
The reasoan is that I want to do the cycle delays etc. by myself so
simply lets say I want to write the value 0x9090 to D0-D15 and these
values shoul remain there as long as I want.

You can configure the External Data Bus as Flags. I would have to look up the specific register settings since I don't generally do this but you will find it in the manual. Al Clark Danville Signal Processing, Inc.
