Dear All,

I am usign a 16 bit memory device with EMI.

The device works only when i use the buffered mode in my MCU. But if i de-comment the #define Buffered in my 91x_conf.h in Keil, all the other functions of MCu stop working. i am not even able to toggle a pin in buffered mode.

Can some one help me by telling how to use buffered mode....

And if some one can tell what/where is Control register - CP15 in STR9.

Thanks.
