It's driving the discussion away from the original question, which is,

"Please give me detailed explanation on Memory Mapped IO(MMIO). I have a great on ambiguity on Hardware connection for MMIO and Hardware Registers."

Dwelling on Lynn's misstatement isn't going to help answer the O/P's question.

Unfortunately, with the proliferation of internal peripherals, and the emphasis on using bleeding edge strategies, the notions of address decoding and timing are being ignored. This fellow wants to learn about them. Isn't it reasonable to attempt to help him with that, rather than having "yet another food-fight" over who's right and who's wrong?
