#160150 - I assume that you have external RAM Responding to: ???'s previous message |
Please describe your hardware. An 8252 could run many programs with no need for external RAM. It just uses its internal RAM and stores non-volatile data in its internal EEPROM. And the program is run from its internal FLASH.
By the look of your program fragment, you have external RAM. This is a totally different space to your program memory in FLASH. Unless of course you are using an "unconventional" memory scheme. EEPROM is addressed from 0 in its own space. The data sheet shows how to access EEPROM. David. |
