 		 #180771 - automatic address recognition on 8051
Hi guys,
I am trying to utilise the auto address recognition feature in the 8051, but am struggling to understand the concept. I understand that you write the address of your device to SADDR register with your mask byte in the SADEN register, but where is the address in the 8-bit UART message found? each frame is sent as 8-bits along with a start and stop bit so where do you put your address so that the device can filter out messages only intended for it? I also dont really understand the concept of the broadcast address
hope someone can help
Thanks

   8-bit or 9-bit?            01/01/70 00:00

      You need both 9-bit *and* the "Enhanced" UART            01/01/70 00:00      
         I guess he has the enhanced            01/01/70 00:00      
            Indeed!            01/01/70 00:00      
               rephrase            01/01/70 00:00      
   which chip?            01/01/70 00:00      
      Aside: multi-UART chips not necessarily all Enhanced?            01/01/70 00:00

               Did you check the link I mentioned?            01/01/70 00:00      
                  risky suggestion            01/01/70 00:00      
                     Yes - staying in the 9-bit mode            01/01/70 00:00
