MC9S12DP256 — Revision 1.1
Glossary
latch — A circuit that retains the voltage level (logic 1 or logic 0) written
to it for as long as power is applied to the circuit.
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
DD
).
logic 0 — A voltage level approximately equal to the ground voltage
(V
SS
).
low byte — The least significant eight bits of a word.
M68HC12 — A Motorola family of 16-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 in integrated circuit fabrication to
transfer an image onto silicon.
MCU — Microcontroller unit. See “microcontroller.”
