Hi i am using MC9s12xdp512 micro controller in my project. I am interface RAM and FPGA to External bus interface of MC9s12xdp512. If Any body is worked on this micro controller. please help me writing software driver of External bus interface on MC9s12xdp512.

Thanks Rob for responding my query..
I have written driver for EBI, I am using 16 bit Data bus, my problem i am not getting UDS correctly. Its not toggling for even and odd address. I am always getting UDS = 0 for even and odd address. I have enabled EBICTL0 & EBICTL1 register, along with these register i have enabled in MCCTL0 & MCCTL1 registers. I am operating my controller in Normal expanded mode only.
Regards,
V. Naresh Kumar
