The Bus Matrix of the AT91SAM9R64/RL64 product manages 6 masters, which means that
each master can perform an access concurrently with others, to an available slave.
Each master has its own decoder, which is defined specifically for each master. In order to sim-
plify the addressing, all the masters have the same decodings.
