Disabling ROM & EEPROM of 68HC11E9 to be used in expande

Postby acar » Fri Apr 21, 2006 3:51 pm

How do I disable ROM & EEPROM of 68HC11E9? Somehow I can't modify the CONFIG register. I want to use an Adapt11EVBU in expanded mode with a 32Kb of NVRAM at location $8000 (upper half of memory space). Also, which option of the Microload menu should I use to download my prgram?

Thanks, in advance, for your help.

You need to use either PCBUG11 or JBUG11 to help disable internal ROM and EEPROM.

Under Microload you can either select Microcore11 or AdaptC24DX both of which uses expanded bus with external memories
