8XC196LX SUPPLEMENT

sample time uncertainty	The variation in the sample time.
sample window	The period of time that begins when the sample
	capacitor is attached to a selected channel of an A/D
	converter and ends when the sample capacitor is
	disconnected from the selected channel.
sampled inputs	All input pins, with the exception of RESET#, are
	sampled inputs. The input pin is sampled one state
	time before the read buffer is enabled. Sampling
	occurs during PH1 (while CLKOUT is low) and
	resolves the value (high or low) of the pin before it is
	presented to the internal bus. If the pin value changes
	during the sample time, the new value may or may not
	be recorded during the read.
	RESET# is a level-sensitive input. EXTINT is
	normally a sampled input; however, the powerdown
	circuitry uses EXTINT as a level-sensitive input
	during powerdown mode.
SAR	Successive approximation register. A component of
	the A/D converter.
set	The “1” value of a bit or the act of giving it a “1”
	value. See also clear.
SFR	Special-function register.
SHORT-INTEGER	An 8-bit, signed variable with values from –2 7
	through +27–1.
sign extension	A method for converting data to a larger format by
	filling the upper bit positions with the value of the
	sign. This conversion preserves the positive or
	negative value of signed integers.
sink current	Current flowing into a device to ground. Always a
	positive value.
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).
