Does it affects the setting on mode pin even access to the I/O registers?

Latest Updated:06/20/2013

Question:

Is even access to the I/O registers affected by the setting on the mode pin (MDE)?

Answer:

The addresses of I/O registers are fixed, and this is regardless of whether the setting on the MDE pin is for little endian or big endian. Accordingly, changes to the endian do not affect access to I/O registers.
For the arrangements of I/O registers, refer to the descriptions of registers in the relevant sections.
