4. The PCI-X Target accepts write data until the write buffer fills or the transaction ends.
5. The PCI-X Target then sends a transaction request to the Linkage Module.
6. After arbitration, the Linkage Module passes the command information, address
7. The VME Master completes the write transaction to the addressed VMEbus slave.
Transaction Termination
The PCI-X Target can terminate a transaction with many of the terminations defined in the
PCI-X Specification. For read requests, PCI-X Target uses split read terminations.
The PCI-X Target terminates a transaction with a retry in the following cases:
•
•
The PCI-X Target terminates a transaction with a disconnect on an address data boundary
(ADB) in the following cases:
•
•
information, and the write data to a VME Master write buffer.
The transaction is a memory write and the write buffer is full.
The transaction is a read and the read buffer command queue is full
A transfer reaches the end of a target image
A burst write fills the write buffer
Having two sets of write buffers allows the VME Master to accept two write
commands and data from the Linkage Module.
