logical address
An 8-bit number that uniquely identifies each VXIbus device in a system.
It defines the A16 register address of a device, and indicates Commander
and Servant relationships.
M
m

master
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.
master-mode operation
A device is in master mode if it is performing a bus cycle which it initiated.
MB
Megabytes of memory
MBLT
Eight-byte block transfers in which both the Address bus and the Data bus
are used to transfer data.
message-based device
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.
MITE
A National Instruments custom ASIC, a sophisticated dual-channel DMA
controller that incorporates the Synchronous MXI and VME64 protocols to
achieve high-performance block transfer rates.
MODID
Module Identification lines
MTBF
Mean Time Between Failure
MXI-2
The second generation of the National Instruments MXIbus product line.
MXI-2 expands the number of signals on a standard MXIbus cable by
including VXI triggers, all VXI interrupts, CLK10, SYSFAIL*,
SYSRESET*, and ACFAIL*.
