Forum Post: GPMC 8bit AD muxed

$

In my system OMAP4  GPMC is comment to a FPGA in a 8 bit mode

ie AD0 ~ AD7, ALEn,WEn,OEn,CS2n. I have only this much connection to my FPGA(save my FPGA pin count).

GPMC is configured as

Asynchronous, 8bit, AD muxed, Base Adress 0x0100_0000, Size 16MB

Can i asume since we have only 8 bit adress line in Adress phase(ALE = 0) the memory acess will wrap around on every 256 location. ie  0x01000_0004 and 0x0100_0104 will give same address in address space or any internal exception will occur in OMAP4.
