Technical Data — MC68HC908GR8
A — See “accumulator (A).”
accumulator (A) — An 8-bit general-purpose register in the CPU08. The CPU08 uses the
acquisition mode — A mode of PLL operation during startup before the PLL locks on a
address bus — The set of wires that the CPU or DMA uses to read and write memory locations.
addressing mode — The way that the CPU determines the operand address for an instruction.
ALU — See “arithmetic logic unit (ALU).”
arithmetic logic unit (ALU) — The portion of the CPU that contains the logic circuitry to perform
asynchronous — Refers to logic circuits and operations that are not synchronized by a common
baud rate — The total number of bits transmitted per unit of time.
BCD — See “binary-coded decimal (BCD).”
binary — Relating to the base 2 number system.
binary number system — The base 2 number system, having two digits, 0 and 1. Binary
binary-coded decimal (BCD) — A notation that uses 4-bit binary numbers to represent the 10
bit — A binary digit. A bit has a value of either logic 0 or logic 1.

reference signal.
arithmetic is convenient in digital circuit design because digital circuits have two
permissible voltage levels, low and high. The binary digits 0 and 1 can be interpreted to
correspond to the two digital voltage levels.
