EMI Electromagnetic Interference
expansion ROM An onboard EEPROM that may contain device-specific initialization
and system boot functionality.
external controller In this configuration, a plug-in interface board in a computer is
connected to the VXI mainframe via one or more VXIbus extended
controllers. The computer then exerts overall control over VXIbus
system operations.
F
fair requester A MXIbus master that will not arbitrate for the MXIbus after releasing
it until it detects the bus request signal inactive. This ensures that all
requesting devices will be granted use of the bus.
H
hex Hexadecimal; the numbering system with base 16, using the digits 0 to
9 and letters A to F.
Hz hertz; cycles per second.
I
IC Integrated Circuit

I/O input/output; the techniques, media, and devices used to achieve
communication between machines and users.
interrupt A means for a device to request service from another device.
interrupt handler A VMEbus functional module that detects interrupt requests generated
by Interrupters and responds to those requests by requesting status and
identify information.
interrupt level The relative priority at which a device can interrupt.
IRQ* Interrupt signal
