Can someone please help me to sort it out?Please 

I am stuck at a project.In the attached code I am unable to wake up the code  after sleep.Rest of the functions working once in sleep it shoild wakeup at if(MV>20)

As I said before, you should not enter sleep mode in an interrupt handler. In this case in TIM2 interrupt handler. I know that you also call EnterSleepMode() from main, but I don't know which one is executed first.

And you should not start with a complex program and expect it will work. I believe that you use PD5 pin as the wakeup event. Did you test before and without sleep mode, if this pin generates an interrupt?
