Yes I am not talking accessing the internal RAM (That works fine for me the ERAM). The problem is I am trying to access an external chip (Philips). Our hw engineer says that a latch is not required as there is an ALE signal that comes out of my ATMEL chip that is connected to the philips chip's ALE pin.

So he says there should be something that I am missing from the software side. The philips chip is a MFRC531 chip.

I strongly suspect the hw connections. So I wanted to confirm that there is nothing more that could be done from the software side.
