fetch — To copy data from a memory location into the accumulator.
firmware — Instructions and data programmed into nonvolatile memory.
free-running counter — A device that counts from zero to a predetermined number, then rolls
full-duplex transmission — Communication on a channel in which data can be sent and
hexadecimal — Base 16 numbering system that uses the digits 0 through 9 and the letters A
high byte — The most significant eight bits of a word.
illegal address — An address not within the memory map
illegal opcode — A nonexistent opcode.
index registers (IX and IY) — Two 16-bit registers in the CPU. In the indexed addressing
input/output (I/O) — Input/output interfaces between a computer system and the external world.
