#110753 - Look up old Intel databook( ~198x) Responding to: ???'s previous message |
You will see schematics of how to map external RAM into both the code and data memory space. This allows you load code in external RAM as data and then run it as code. If it is a kit by company like Anshuman, the user guide shows the schematic of how it is done. In fact this kit works with any vanilla variety of 8051( that is 8051, 52, 89C52 etc) because the EA pin is grounded, so it always accesses the external memory. |
