V — The 0-volt dc power supply return for a microcontroller.
SS
Word — A group of binary bits. Some larger computers consider a set of
16 bits to be a word but this is not a universal standard.
X — Abbreviation for index register, a CPU register in the MC68HC908RK2.
Z — Abbreviation for zero, a bit in the condition code register of the
MC68HC908RK2. A compare instruction subtracts the contents of the
tested value from a register. If the values were equal, the result of this
subtraction would be 0 so the Z bit would be set; after a load
accumulator instruction, the Z bit will be set if the loaded value was
$00.
