AT89C51RE2 clarification

2 UART. but in the uVision V3.33 debugger peripherals i dont see that i have 2 UART to work with.

why ?

thanks in advance

    You would have to ask Keil that!

    But, if you look at the list of "supported" devices, you will see that it's huge - and, therefore, it would be an absolutely monumental task to provide detailed simulation for every single detail of every single feature of every single chip...!

    "how it could affect me in case i want to simulate both UART simultaneously ?"

    If it doesn't support simulating the 2nd UART then, obviously, you just can't do it!

    However, uVision does provide simulation for the 2nd UART on some other chips - so you might find one that is close enough for your purposes...

    Alternatively, you may be able to do it yourself by accessing the SFRs directly - see:
    http://www.keil.com/support/man/docs/uv3/uv3_debug_functions.htm
    www.keil.com/.../uv3_df_signalfunctions.htm

    Or, as Per says, just do it on real hardware!
