A functional part of a MXI/VME/VXIbus device that initiates data
transfers on the backplane. A transfer can be either a read or a write.
A device is in master mode if it is performing a bus cycle which it
initiated.
An intelligent device that implements the defined VXIbus registers and
communication protocols. These devices are able to use Word Serial
Protocol to communicate with one another through communication
registers.
