Is access I/O registers affect endian select registers (MDEB/MDES)

Latest Updated:01/23/2014

Question:

Is access to the I/O registers affected by the endian set in the endian select registers (MDEB and MDES)?

Answer:

Access to the I/O registers is not affected by the endian set in the endian select registers. However, each I/O register must be accessed in the access size designated for that register.

For I/O register access sizes, please see I/O Register Addresses in the I/O Registers chapter of the User's Manual: Hardware.
