EPROM — Erasable, programmable, read-only memory. A non-volatile type of memory that can
exception — An event such as an interrupt or a reset that stops the sequential execution of the
external interrupt module (IRQ) — A module in the M68HC08 Family with both dedicated
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
H — The upper byte of the 16-bit index register (H:X) in the CPU08.
H — The half-carry bit in the condition code register of the CPU08. This bit indicates a carry from
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.
I — The interrupt mask bit in the condition code register of the CPU08. When I is set, all interrupts
