Example PCI-X Write Transaction
In this example PCI-X-to-VME write transaction, the data passes through Tsi148 through the
PCI-X Target, to the Linkage Module, and ends at the VME Master. The following list, and

2. The PCI-X Target puts the address and command information in its write buffer
3. The PCI-X Target puts the corresponding data into its data queue
command queue
— All write transactions are posted within the PCI-X Target write buffer data queue.
