The interconnect transaction attributes include the data and address widths, as well as the AxCache, AxUser, and AxProt command signals that accompany the transaction request as defined by the Arm® AMBA® AXI and ACE Protocol Specification.
Transactions are initiated with several types of attributes in addition to an address and a read/write request. The transaction attribute settings and options for each source are described in the following sections.
Note: Not all
parameters apply to all transactions. Some transactions have fixed attribute signal
values while others have signal values that can be configured dynamically.
