Example PCI-X Read Transaction
In this example PCI-X-to-VME read, the transaction is separated into Request and
Completion phases. The following list, and
the transaction (Request). The second part of the list, and
transaction (Completion).
1. A PCI-X master initiates a read request to a VMEbus slave
2. The Tsi148 PCI-X Target decodes the request and issues a Split Response termination to
3. The PCI-X Target stores the command, address, and attribute information in the PCI-X
