I cant able to fuse the code in chip(p89v51rd2) using flash magic. It always diplay like "reset device to ISP mode now". Kindly help me regarding this.
its the processor speed constant. it is very clever because you dont need to change the loop when you change the processor. just change the "k"onstant value. i have lots of code improvement hints at www.saralamcodingstandards.com/theverybest
But that "clever" constant is incorrectly placed, so it doesn't do what you claim it to do.
And there are still no side effects generated by the function, so the compiler can still throw away everything.
