I am told to design a generic microprocessor interface for a ASIC chip. Since I am not familiar with what types/modes of microprocessor are most popular, I don't know how generic I can reach.
I am aware of there are synchronous/asychronous modes, separate or mux address/data modes. But I notice there are so many different families and series. Would somebody point me some typical families of Microprocessor or even its datasheet?
