Move many, useful when you want to save a bunch of registers, for example to save their value when branching to a function it moves a list of registers to memory, or memory to a list of registers. The first operand is the list of registers, the second operand is the memory region. If you define the registers as the first operand, then it will save the registers to memory, if the first operand is the memory, then it will load the registers from memory. You can write the list of registers by separating them with a "/", and the range between registers by using a dash. ex: a3-a5/d0-d2 will select d0, d1, d2, a3, a4, a5. The order of the register will be converted to first data, then address registers, from 0 to 7. When using the pre-decrement operand, the order of the registers will be reversed, going from a7 to a0, and d7 to d0.
