microcontroller — Microcontroller unit (MCU). A complete computer system, including a CPU,
modulo counter — A counter that can be programmed to count to any number from zero to its
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
Motorola scalable CAN (msCAN) — The Motorola scalable controller area network is a serial
msCAN — See "Motorola scalable CAN".

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.
