Example VME Slave Read Transaction
In this example VME-to-PCI-X read, the transaction is separated into Request and
Completion phases. The following list, and
the transaction (Request) and in the second part of the list, and
of the transaction (Completion).
1. A VMEbus master initiates a SCT, BLT, MBLT, 2eVME, or 2eSST read request to a
2. Tsi148 stores the command and address information, as well as byte count information (if
PCI/X peripheral.
it is a a 2eVME or 2eSST request) in the VME Slave’s read buffer command queue
— Tsi148 supports one read request at a time
