M68ICS05COM/D
A microcontroller whose data is communicated over a data bus
made up of eight separate data conductors. Members of the
M68HC05 family of microcontrollers are 8-bit MCUs.
Abbreviation for the accumulator of the M68HC05 MCU.
An 8-bit register of the M68HC05 CPU. The contents of this
register may be used as an operand of an arithmetic or logical
instruction.
Software program that translates source code mnemonics into
opcodes that can then be loaded into the memory of a
microcontroller.
Instruction mnemonics and assembler directives that are
meaningful to programmers and can be translated into an object
code program that a microcontroller understands. The CPU uses
opcodes and binary numbers to specify the operations that make up
a computer program. Humans use assembly language mnemonics
to represent instructions. Assembler directives provide additional
information such as the starting memory location for a program.
Labels are used to indicate an address or binary value.
American Standard Code for Information Interchange. A widely
accepted correlation between alphabetic and numeric characters
and specific 7-bit binary numbers.
During debugging of a program, it is useful to run instructions until
the CPU gets to a specific place in the program, and then enter a
debugger program. A breakpoint is established at the desired
address by temporarily substituting a software interrupt (SWI)
instruction for the instruction at that address. In response to the
SWI, control is passed to a debugging program.
A set of exactly eight binary bits.
Abbreviation for “carry/borrow” in the condition codes register of
the M68HC05. When adding two unsigned 8-bit numbers, the C bit
is set if the result is greater than 255 ($FF).
