8XC196LX SUPPLEMENT

external address	A 21-bit address is presented on the microcontroller’s
	pins. The address decoded by an external device
	depends on how many of these address pins the
	external system uses. See also internal address.
f	Lowercase “f” represents the frequency of the internal
	clock.
far constants	Constants that can be accessed only with extended
	instructions. See also near constants.
far data	Data that can be accessed only with extended instruc-
	tions. See also near data.
feedthrough	The attenuation from an input voltage on the selected
	channel to the A/D output after the sample window
	closes. The ability of the A/D converter to reject an
	input on its selected channel after the sample window
	closes.
FET	Field-effect transistor.
full-scale error	The difference between the ideal and actual input
	voltage corresponding to the final (full-scale) code
	transition of an A/D converter.
hold latency	The time it takes the microcontroller to assert HLDA#
	after an external device asserts HOLD#.
ideal characteristic	The characteristic of an ideal A/D converter. An ideal
	characteristic is unique: its first code transition occurs
	when the input voltage is 0.5 LSB, its full-scale (final)
	code transition occurs when the input voltage is 1.5
	LSB less than the full-scale reference, and its code
	widths are all exactly 1.0 LSB. These properties result
	in a conversion without zero-offset, full-scale, or
	linearity errors. Quantizing error is the only error
	seen in an ideal A/D converter.
input leakage	Current leakage from an input pin to power or ground.
input series resistance	The effective series resistance from an analog input
	pin to the sample capacitor of an A/D converter.
integer	Any member of the set consisting of the positive and
	negative whole numbers and zero.
INTEGER	A 16-bit, signed variable with values from –2 15
	through +215–1.
