Hi, i would like to know if i can change the sizerom in an at89c51ed2. I know in dallas microcontrollers family you can select the romsize using ROMSIZE register. I would like to know if i can use similar register in at89c51ed2. I need use 8k of rom with mon51 to simulate or use 64k of rom to execute the program. thanks tribbi
1. AT89C51ED2 allows to adjust XRAM size only. 2. The only ROM of AT89C51ED2 I know is the bootloader 2kb ROM. Do you mean EEPROM, Flash or what? 3. why not use uVision options to define code size? Regards, Oleg
"The only ROM of AT89C51ED2 I know is the bootloader 2kb ROM" Even that is probably really flash.
