#92056 - Code banking (HUGE) 80251 + PSD834
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
