USB Host Controller expects that data are compiled from lower address to upper address
regardless endian setting of the CPU. Below figure shows data read operation which is done by
USB Host Controller.
The correspondence between data in memory and data read by USB Host Controller must be
equal. When USB Host Controller reads data from external memory, USB Host Controller reads
data by long word read operation every time regardless that the read data are written in byte ,word
or long word. USB Host Controller uses data in byte from lower address in long word which it
reads regardless the endian mode. Even endian mode is set as big or little, set the data from down
addresses.
Below program flow is the example of failure.

In program, set transfer address A to register R0 at big endian
In program, “MOV.B #H'12,@R0”
In program , set transfer start address A to USB Host Controller , and set 1byte as transfer
