i have found that in the DataSheet of the 8051 from Atmel the havent shown that their 8051 based MCU's had two Registers which are essential for Automatic Address Recoganization, that are SADDR and SADDEN , so could any one tell me that how to confirm that these MCUs have "Automatic Address Recoganization"

The Automatic Address Recognition is an extended feature - if the devices don't have the necessary registers, then they don't support it.

See: http://www.8052.com/forum/read.phtml?id=104456

Be sure to check the Datasheet for the specific device that you are using - not just some generic "family" document.
