SAM9260 [SUMMARY]
6221LS–ATARM–15-Oct-12
Boot Mode Select
Non-volatile Boot Memory can be internal or external
Selection is made by BMS pin sampled at reset
Remap Command
Allows Remapping of an Internal SRAM in Place of the Boot Non-Volatile Memory
Allows Handling of Dynamic Exception Vectors
7.2.1
Matrix Masters
The Bus Matrix of the SAM9260 manages six Masters, which means that each master can perform an access
concurrently with others, according the slave it accesses is available.
Each Master has its own decoder that can be defined specifically for each master. In order to simplify the addressing, all
the masters have the same decodings.
7.2.2
Matrix Slaves
Each Slave has its own arbiter, thus allowing a different arbitration per Slave to be programmed.
7.2.3
Master to Slave Access
All the Masters can normally access all the Slaves. However, some paths do not make sense, such as allowing access
from the Ethernet MAC to the Internal Peripherals. Thus, these paths are forbidden or simply not wired, and shown “-” in
the following table.
