We are implementing external flash memory (Numonyx 16MB exterrnal flash memory) using External Bus Interface of microcontroller MC9S12XEQ512 in our project.  we already have the driver code obtained from Numonyx and made changes in the user section of the driver code based on the variant(which is 160FT variant of Numonyx-16MB) we are using. but still we are unable to access the external flash memory. 

 

It would be much helpful if anyone can post any application notes and application program for the same(external memory interface).
