Bus Matrix
SAM9G46
Matrix Masters
The Bus Matrix of the SAM9G46 manages Masters, thus each master can perform an access
concurrently with others, depending on whether the slave it accesses is available.
Each Master has its own decoder, which can be defined specifically for each master. In order to
simplify the addressing, all the masters have the same decodings.

• 12-layer Matrix, handling requests from 11 masters
• Programmable Arbitration strategy
• Burst Management
• One Address Decoder provided per Master
• Boot Mode Select
• Remap Command
– Fixed-priority Arbitration
– Round-Robin Arbitration, either with no default master, last accessed default master
– Breaking with Slot Cycle Limit Support
– Undefined Burst Length Support
– Three different slaves may be assigned to each decoded memory area: one for
– Non-volatile Boot Memory can be internal ROM or external memory on EBI_NCS0
– Selection is made by General purpose NVM bit sampled at reset
– Allows Remapping of an Internal SRAM in Place of the Boot Non-Volatile Memory
– Allows Handling of Dynamic Exception Vectors
or fixed default master
internal ROM boot, one for internal flash boot, one after remap
