Hello, I have started a new project with a 80c251 microcontroller and PSD834F1 device and I want to use code Banking. I have just implement the following memory map: 0x008000-0x00FFFF EEPROM from PSD 0x018000-0x01FFFF NVRAM External 0xFE0000-0xFEFFFF Code OxFF0000-0xFFFFFF Code But I would like to have code banking with 1 common area and 2 Banks codes: 0x008000-0x00FFFF EEPROM from PSD 0x018000-0x01FFFF NVRAM External 0xFE0000-0xFEFFFF Code (COMMON) OxFF0000-0xFFFFFF Code (BANK0,BANK1) Is it possible to implement this memory map using HUGE memory? Is there any PDF explaning HUGE memory code banking? Any ideas? Regards Jesus Haro
