This section describes PCI single-beat write transactions, and PCI burst write transactions. A PCI write

transaction starts with the address phase, occurring when an initiator asserts PCI_FRAME. A write

transaction is similar to a read transaction except no turnaround cycle is needed following the address

phase because the initiator provides both address and data. The data phases are the same for both read and

write transactions. Although not shown in the figures, the initiator must drive the PCI_C/BE[3:0] signals,

even if the initiator is not ready to provide valid data (PCI_IRDY negated).
