Matrix Masters
Matrix Slaves
SAM9X25
The Bus Matrix of the AT91SAM9X25 product manages 12 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.
Table 6-1.
The Bus Matrix of the AT91SAM9X25 product manages 9 slaves. Each slave has its own arbi-
ter, allowing a different arbitration per slave.
