Glossary
MCU because there is no way to expose the EPROM to a UV light.
PC — Abbreviation for program counter CPU register of the
MC68HC908KX8.
program counter — The CPU register that holds the address of the next
instruction or operand that the CPU will use.
RAM — Random access memory. Any RAM location can be read or written
by the CPU. The contents of a RAM memory location remain valid
until the CPU writes a different value or until power is turned off.
registers — Memory locations that are wired directly into the CPU logic
instead of being part of the addressable memory map. The CPU always
has direct access to the information in these registers. The CPU
registers in the MC68HC908KX8 are A (8-bit accumulator), X (8-bit
index register), CCR (condition code register containing the H, I, N, Z,
and C bits), SP (stack pointer), and PC (program counter). Memory
locations that hold status and control information for on-chip
peripherals are called I/O and control registers.
reset — Reset is used to force a computer system to a known starting point and
to force on-chip peripherals to known starting conditions.
S record — A Motorola standard format used for object code files.
simulator — A computer program that copies the behavior of a real MCU.
source code — See source program.
SP — Abbreviation for stack pointer CPU register in the MC68HC908KX8
MCU.
source program — A text file containing instruction mnemonics, labels,
comments, and assembler directives. The source file is processed by an
assembler to produce a composite listing and an object file
representation of the program.
stack pointer — A CPU register that holds the address of the next available
storage location on the stack.
TTL — Transistor-to-transistor logic.
