Glossary
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,
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).
break interrupt — A software interrupt caused by the appearance on
the internal address bus of the same value that is written in the break
address registers.
bus — A set of wires that transfers logic signals.
bus clocks — There are two bus clocks, IT12 and IT23. These clocks
are generated by the CGM and distributed throughout the MCU by
the SIM. The frequency of the bus clocks, or operating frequency, is

is different.
byte — A set of eight bits.
C — The carry/borrow bit in the condition code register. The CPU08 sets
the carry/borrow bit when an addition operation produces a carry out
of bit 7 of the accumulator or when a subtraction operation requires
a borrow. Some logical operations and data manipulation instructions
also clear or set the carry/borrow bit (as in bit test and branch
instructions and shifts and rotates).
CCR — See condition code register.
