IMHO:

Hi,
Thank you very much! These information help me a lot to make plan for 
our project! 

Furthermore, I have a detail question:

In keil 51 vision 8, during the simulation, in the "option for Target "
-> "device", there are many types of 8052 microcontroller listed(eg. 
Intel 8052AH,ADE7169F16....), which one I should choose? Because I 
want to make the simulation result more closed to t51 rtl code behavior.
In another word, which 8052 microcontroller does t51 rtl code describe?
what is its reference model?

Thanks in advance!

wwang
