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
MOTOROLA
accumulator to hold operands and results of arithmetic and logic operations.
frequency. Also see "tracking mode."
The M68HC08 CPU has 16 addressing modes.
arithmetic, logic, and manipulation operations on operands.
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.
