Section 6. Glossary
A
— See “accumulator (A).”
accumulator (A)
— An 8-bit general-purpose register in the CPU08. The CPU08 uses the accumulator
to hold operands and results of arithmetic and logic operations.
acquisition mode
— A mode of PLL operation during startup before the PLL locks on a frequency. Also
see “tracking mode.”
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. The
M68HC08 CPU has 16 addressing modes.
ALU
— See “arithmetic logic unit (ALU).”
arithmetic logic unit (ALU)
— The portion of the CPU that contains the logic circuitry to perform
arithmetic, logic, and manipulation operations on operands.
asynchronous
— Refers to logic circuits and operations that are not synchronized by a common
reference signal.
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 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.
binary-coded decimal (BCD)
— A notation that uses 4-bit binary numbers to represent the 10 decimal
digits and that retains the same positional structure of a decimal number. For example,
234 (decimal) = 0010 0011 0100 (BCD)
bit
— A binary digit. A bit has a value of either logic 0 or logic 1.
branch instruction
— An instruction that causes the CPU to continue processing at a memory location
other than the next sequential address.
break module
— A module in the M68HC08 Family. The break module allows software to halt program
execution at a programmable point in order to enter a background routine.
breakpoint
— A number written into the break address registers of the break module. When a number
appears on the internal address bus that is the same as the number in the break address registers,
the CPU executes the software interrupt instruction (SWI).
