Intel 80C196NU, 8XC196NP, Microcontroller manual Glossary

GLOSSARY

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

1-Mbyte mode	The addressing mode that allows code to reside
	anywhere in the 1-Mbyte addressing space.
64-Kbyte mode	The addressing mode that allows code to reside only
	in page FFH.
accumulator	A register or storage location that forms the result of
	an arithmetic or logical operation.
	The 80C196NU has enhanced multiplication instruc-
	tions that use a new 32-bit accumulator for multiply-
	accumulate operations.
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.
bit	A binary digit.
BIT	A single-bit operand that can take on the Boolean
	values, “true” and “false.”
byte	Any 8-bit unit of data.
BYTE	An unsigned, 8-bit variable with values from 0
	through 28–1.
CCBs	Chip configuration bytes. The chip configuration
	registers (CCRs) are loaded with the contents of the
	CCBs after a device reset.
CCRs	Chip configuration registers. Registers that define the
	environment in which the device will be operating.
	The chip configuration registers are loaded with the
	contents of the CCBs after a device reset.
