Figure 1-4. Master Read Transaction Phases
The slave creates a read transaction by calling the create_slave_transaction() task to accept the
transfer of read information from the master. The slave accepts the address phase by calling the
get_read_addr_phase() task, and then executes the data burst phase by calling the
execute_read_data_phase() task as illustrated in Figure 1-5 .
