ARM Cortex-M4 Processor
APB/AHB bridge
Matrix Masters
Matrix Slaves
The SAM4S embeds One Peripheral bridge.
The peripherals of the bridge are clocked by MCK.
The Bus Matrix of the SAM4S manages 4 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 7-1.
The Bus Matrix of the SAM4S manages 5 slaves. Each slave has its own arbiter, allowing a dif-
ferent arbitration per slave.
