Glossary
instructions — Operations that a CPU can perform. Instructions are expressed by programmers
interrupt — A temporary break in the sequential execution of a program to respond to signals
interrupt request — A signal from a peripheral to the CPU intended to cause the CPU to
I/O — See “input/output (I/0).”
IRQ — See "external interrupt module (IRQ)."
jitter — Short-term signal instability.
latch — A circuit that retains the voltage level (logic 1 or logic 0) written to it for as long as power
latency — The time lag between instruction completion and data movement.
least significant bit (LSB) — The rightmost digit of a binary number.
logic 1 — A voltage level approximately equal to the input power voltage (V
logic 0 — A voltage level approximately equal to the ground voltage (V
low byte — The least significant eight bits of a word.
low voltage inhibit module (LVI) — A module in the M68HC08 Family that monitors power
LVI — See "low voltage inhibit module (LVI)."
M68HC08 — A Motorola family of 8-bit MCUs.
mark/space — The logic 1/logic 0 convention used in formatting data in serial communication.
mask — 1. A logic circuit that forces a bit or group of bits to a desired state. 2. A photomask used
