Hi, I have a question regarding EMA_BA[1:0], both programming and logical addressing?

I am actually interfacing an external asynchronous UART using EMIF. I want to ask what actually happens on EMA_BA[1:0] pins, if I try to access it using EMIF. Or what is the actual program and logical address scheme? How will those EMA_BA[1:0] and EMA_A[13:0] will behave?

Thanks
