1. A logic function that uses a binary value, or address, to select between a number of inputs
2. A technique which allows different input (or output) signals to use the same lines at different

A transition from a logic 1 to a logic 0. Also known as a falling edge.
The routing between devices.
A group of four bits, which is one-half of a byte.
1. A disturbance that affects a signal and that may distort the information carried by the signal.
2. The random variations of one or more characteristics of any entity such as voltage, current,

A circuit that may be crystal controlled and is used to generate a clock frequency.
The electrical signal or signals which are produced by an analog or digital block.
The means of communication in which digital data is sent multiple bits at a time, with each simul-
taneous bit being sent over a separate line.
Characteristics for a given block that have either been characterized or may be defined by the
designer.
A location in memory where parameters for the SSC instruction are placed prior to execution.
A technique for testing transmitting data. Typically, a binary digit is added to the data to make the
sum of all the digits of the binary data either always even (even parity) or always odd (odd par-
ity).
1. The logical sequence of instructions executed by a computer.
2. The flow of an electrical signal through a circuit.
An interrupt that has been triggered but has not been serviced, either because the processor is
busy servicing another interrupt or global interrupts are disabled.
