GLOSSARY

This glossary defines acronyms, abbreviations, and terms that have special meaning in this man- ual. (Chapter 1 discusses notational conventions and general terminology.)

absolute error	The maximum difference between corresponding
	actual and ideal code transitions. Absolute error
	accounts for all deviations of an actual A/D converter
	from an ideal converter.
accumulator	A register or storage location that forms the result of
	an arithmetic or logical operation.
actual characteristic	A graph of output code versus input voltage of an
	actual A/D converter. An actual characteristic may
	vary with temperature, supply voltage, and frequency
	conditions.
A/D converter	Analog-to-digital converter. An internal peripheral
	that converts an analog input to a digital value.
ALU	Arithmetic-logic unit. The part of the RALU that
	processes arithmetic and logical operations.
assert	The act of making a signal active (enabled). The
	polarity (high or low) is defined by the signal name.
	Active-low signals are designated by a pound symbol
	(#) suffix; active-high signals have no suffix. To
	assert RD# is to drive it low; to assert ALE is to drive
	it high.
attenuation	A decrease in amplitude; voltage decay.
bit	A binary digit.
BIT	A single-bit operand that can take on the Boolean
	values, “true” and “false.”
bit arbitration	The process of settling conflicts that occur when
	multiple nodes attempt to transmit a bit or symbol
	across a single bus at the same time.
break-before-make	The property of a multiplexer which guarantees that a
	previously selected channel is deselected before a
	new channel is selected. (That is, break-before-make
	ensures that the A/D converter will not short inputs
	together.)
