    Hi everybody!!!!!

    I’m new in this forum nice to meet you too!!!!!

     

    I’m try to understand a kind of instructions for my 8052 platform  ( I program an ADUC836  Analog/Devices ) and i wanted top know if you could give me some help!!!

     

    The instructions it’s an access inside the EE/Flash with the EDATA1 – EDATA4 sfr register and it’s  the follow:

     

     

     

    data int variable;

     

    EDATA1 = *( (unsigned char data *) ( &variable ) );

    EDATA2 = *(((unsigned char data *) (&variable) ) +1);

     

    What we try to do with this statement?

     

    Thank you everybody!!!smiley
