3.2.1 Data Movement Instructions
3-4
The MOVE instructions with their associated addressing modes are the basic
means of transferring and storing addresses and data. MOVE instructions
transfer byte, word, and long-word operands from memory to memory, mem-
ory to register, register to memory, and register to register. Address move-
ment instructions (MOVE or MOVEA) transfer word and long-word operands
and ensure that only valid address manipulations are executed. In addition
to the general MOVE instructions, there are several special data movement
instructions: move multiple registers (MOVEM), move peripheral data
(MOVEP), move quick (MOVEO), exchange registers (EXG), load effective
address (LEA), push effective address (PEA), link stack (LINK), and unlink
stack (UNLK).
