Kedar, There is no istruction called bfread. The instruction set for the Motorola DSP's can be found in the DSP56800 Family Manual. You would use this manual if you are using the 56800 family. Here is a link for the manual: http://e-www.motorola.com/files/dsp/doc/ref_manual/DSP56800FM.pdf You can also try this link: http://e-www.motorola.com/webapp/sps/site/prod_summary.jsp? code=DSP56F805&nodeIdz6wYqRXz6292 and scroll down to 'Reference Manual' and you will find the DSP56800 Family Manual. If you are using the DSP56800E Family you would use 'DSP56800E Reference Manual'. Here is the link for the document: http://e-www.motorola.com/files/dsp/doc/ref_manual/DSP56800ERM.pdf You can also use this link: http://e-www.motorola.com/webapp/sps/site/prod_summary.jsp? code=DSP56858&nodeIdz6wYqRXz3011 under 'Reference Manual' you will see the aforementioned document. I hope that this helps.
