Oleg Sergeev thanks a lot , now i have registered 8052.com so iam putting my question in a simplified way actually the scheme you are refereing is good for such project where the states for a signal bit are less but in my case there are lots of state for a bit and furthere data has to be sent for different bits and for that lookup tables are need to be managed for that iam placing another thread.

But iam thankful to all of those all replied and gave me your important time which forced me to join this web.

regards,
Amir Hayat
