VME Slave Write Transaction
During write transactions, the external master posts write data into the write buffer. All writes
are posted and the write buffer stores the data necessary to complete the transfer and
immediately acknowledges the transaction on the VMEbus. Tsi148 manages the completion
of the posted write transaction.
— If the AS signal is asserted and the refill threshold has been reached in the VME
Slave’s read buffer data queue, the VME Slave requests the Linkage Module to
return to the PCI/X bus for more data.
