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 transaction have fixed attribute signal values while others have signal values that can be configured dynamically.

The transaction attribute signals include the following.

Transactions from the LPD hosts can be individually routed directly to memory or to the FPD SMMU TBUs and the CCI for shared memory and coherent transactions.
