I am using P89V51RD2 and I want a description about the memory models. I want to use the whole 1KB RAM of the controller. I tried to search for the memory model, but was confused by the data given on the page below.
www.esacademy.com/.../c02.htm
It says that you can only access 256 bytes of RAM even though you use LARGE model. Can anyone figure it out?
