The detection of conflicting symbols or bits on the
bus.
See off-isolation.
Leakage current from an analog input pin to ground or
to the reference voltage (V
The act of making a signal inactive (disabled). 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
deassert RD# is to drive it high; to deassert ALE is to
drive it low.
The configuration in which the microcontroller uses
separate lines for address and data (address on A20:0;
data on AD15:0 for a 16-bit bus or AD7:0 for an 8-bit
bus). See also multiplexed bus.
The difference between the actual code width and the
ideal one-LSB code width of the terminal-based
characteristic of an A/D converter. It provides a
measure of how much the input voltage may have
changed in order to produce a one-count change in the
conversion result. Differential nonlinearity is a
measure of local code-width error; nonlinearity is a
measure of overall code-transition error.
The process of introducing a periodic table Group III
or Group V element into a Group IV element (e.g.,
silicon). A Group III impurity (e.g., indium or
gallium) results in a p-type material. A Group V
impurity (e.g., arsenic or antimony) results in an n-
type material.
Any 32-bit unit of data.
An unsigned, 32-bit variable with values from 0

Event processor array. An integrated peripheral that
provides high-speed input/output capability.
