#60267 - 89C51RC and Keil
Hello,

since I overgrew my old 89s53 I want to switch to 89C51RC. I have a question about accessing extra 256 bytes of RAM. Is this PDATA? Do I declare variables to PDATA. Where is then stack starting? On 256 or 512? I think it starts on 256 (IDATA), so I want to move my variables to PDATA. I know I must setup some bits first to access to this segment.

Please correct me if I am wrong.

regards, Damjan
