Hello, I am using AT89C51RD2 for my application and I want to use 1792 byte RAM therein. I have initialized the required register which is AUXR = 0x11 which set RAM to 1792 byte but when I exceed the number of bytes above 1024 programme is not working even though it has 1792 byte of RAM.
Regards, Abhijeet R. Mudgal.
