Intel 8XC196NT, 87C196CB interrupt controller for processing by an interrupt, service routine

87C196CB SUPPLEMENT

source current	Current flowing out of a device from VCC. Always a
	negative value.
SP	Stack pointer.
special interrupt	Any of the three nonmaskable interrupts (unimple-
	mented opcode, software trap, or NMI).
special-purpose memory	A partition of memory used for storing the interrupt
	vectors, PTS vectors, chip configuration bytes, and
	several reserved locations.
standard interrupt	Any maskable interrupt that is assigned to the
	interrupt controller for processing by an interrupt
	service routine.
state time (or state)	The basic time unit of the device; the combined
	period of the two internal timing signals, PH1 and
	PH2. (The internal clock generator produces PH1 and
	PH2 by halving the frequency of the signal on
	XTAL1. The rising edges of the active-high PH1 and
	PH2 signals generate CLKOUT, the output of the
	internal clock generator.) Because the device can
	operate at many frequencies, this manual defines time
	requirements in terms of state times rather than in
	specific units of time.
successive approximation	An A/D conversion method that uses a binary search
	to arrive at the best digital representation of an analog
	input.
temperature coefficient	Change in the stated variable for each degree
	Centigrade of temperature change.
temperature drift	The change in a specification due to a change in
	temperature. Temperature drift can be calculated by
	using the temperature coefficient for the specification.
terminal-based characteristic	An actual characteristic that has been translated and
	scaled to remove zero-offset error and full-scale
	error. A terminal-based characteristic resembles an
	actual characteristic with zero-offset error and full-
	scale error removed.
transfer function	A graph of output code versus input voltage; the
	characteristic of the A/D converter.
