I'm looking at using the 9S12XDP512CAG. While working out the connections for all of my peripherals, I realize that I'll need to make use of the IIC that is mux'd with CS0 & CS2. My concern is, will this hamper my ability to use external RAM? I've been looking through the datasheet and from what I can tell so far, it doesn't look like there should be any issues. Though I would just like to make sure that neither chip select is special. Thanks.
