Hi,
I am using MC9S12DP256B...
1.  Internal Flash from 0x8000 to 0xBFFF.
2.  External RAM of 64K from 0x4000 to 0x7FFF.
 
To access 256K of flash, I am using paging i.e. 0x30 to 0x3F.
 
My query is:
1. How prm file will be changed to support external RAM.
2. is any thing else has to be done other configuring the system to be in expanded mode???
