Glossary
memory location — Each M68HC12 memory location holds one byte
of data and has a unique address. To store information in a
memory location, the CPU places the address of the location on
the address bus, the data information on the data bus, and
asserts the write signal. To read information from a memory
location, the CPU places the address of the location on the
address bus and asserts the read signal. In response to the read
signal, the selected memory location places its data onto the data
bus.
memory map — A pictorial representation of all memory locations in a
computer system.
MI-Bus — See "Motorola interconnect bus".
microcontroller — Microcontroller unit (MCU). A complete computer
system, including a CPU, memory, a clock oscillator, and
input/output (I/O) on a single integrated circuit.
modulo counter — A counter that can be programmed to count to any
number from zero to its maximum possible modulus.
most significant bit (MSB) — The leftmost digit of a binary number.
Motorola interconnect bus (MI-Bus) — The Motorola Interconnect Bus
(MI Bus) is a serial communications protocol which supports
distributed real-time control efficiently and with a high degree of
noise immunity.
Motorola scalable CAN (msCAN) — The Motorola scalable controller
area network is a serial communications protocol that efficiently
supports distributed real-time control with a very high level of data
integrity.
msCAN — See "Motorola scalable CAN".
