I have checked the IC in default mode it is alive i.e. it is giving a response of 6.25 MHz.I am trying to write a code through which I can write some value into the register and read it back the same value so that I can get a confidence that What I want to write into specific registers it is written correctly. I have tried hard but I am not getting the response.I am attaching a copy of code with this mail. Kindly find the attachment and let us know where I am doing the mistake.SCLK frequency is 25 MHz. It is very Urgent Sir. kindly do the needful as soon as possible.
