1) Least-significant bit of a byte or least-significant
byte of a word.
2) In an A/D converter, the reference voltage divided
n
by 2
, where n is the number of bits to be converted.
For a 10-bit converter with a reference voltage of 5.12
volts, one LSB is equal to 5.0 millivolts (5.12 ÷ 2

interrupts
software trap, and NMI. Maskable interrupts can be
disabled (masked) by the individual mask bits in the
interrupt mask registers, and their servicing can be
disabled by the global interrupt enable bit. Each
maskable interrupt can be assigned to the PTS for
processing.
The property of successive approximation converters
which guarantees that increasing input voltages
produce adjacent codes of increasing value, and that
decreasing input voltages produce adjacent codes of
decreasing value. (In other words, a converter is
monotonic if every code change represents an input
voltage change in the same direction.) Large differ-
ential nonlinearity errors can cause the converter to
exhibit nonmonotonic behavior.
Most-significant bit of a byte or most-significant byte
of a word.
A field-effect transistor with an n-type conducting
path (channel).
Semiconductor material with introduced impurities
(doping) causing it to have an excess of negatively
charged carriers.
An A/D converter has no missing codes if, for every
output code, there is a unique input voltage range
which produces that code only. Large differential
nonlinearity errors can cause the converter to miss
codes.
The maximum deviation of code transitions of the
terminal-based
sponding code transitions of the ideal characteristic.
