Accumulator (ACC, A): ACC is the accumulator register. Most instructions use the accumulator to hold
the operand. The mnemonics for accumulator-specific instructions refer to accumulator as “A”, not ACC.
B Register: The B register is used during multiply and divide instructions. It can also be used as a
scratch-pad register to hold temporary data.
