command that is passed to the Linkage Module
The Linkage Module provides a common interface for all the modules and has the
following ports: VMEbus, PCI bus, DMA 0, DMA1, and registers. The Linkage
Module uses a round-robin arbitration scheme to fairly arbitrate between the ports.
Having two buffers to store data allows the Tsi148 VME Master to do
back-to-back reads on the VMEbus.
