All interrupts except stack overflow, unimplemented
opcode, and software trap. Maskable interrupts can be
disabled (masked) by the individual mask bits in the
interrupt mask registers, and their servicing can be
disabled by the DI (disable interrupt service)
instruction. 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.
Most-significant word of a double-word or quad-
word.
The configuration in which the microcontroller uses
both A20:0 and AD15:0 for address and also uses
AD15:0 for data. See also demultiplexed bus.
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.
Constants that can be accessed with nonextended
instructions. Constants in page 00H are near
constants. See also far constants.
Data that can be accessed with nonextended instruc-
tions. Data in page 00H is near data. See also far data.
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.
