Can I connect the ETB's AHB interface in a big-endian memory system?

Applies to: ETB11

Answer

The AHB interface on the ETB11 is a little-endian interface. This means that if the ETB11 is used in a big-endian memory system and byte or half-word accesses are performed to the ETB11 RAM using the AHB interface then the bytes in the transfer must be rotated. This rotation should either be performed with on-chip logic, or by the software which is accessing the ETB11 RAM.
