Instruction Set Summary
3.1.1 Data Movement Instructions
The MOVE and FMOVE 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, memory to register, register to
memory, and register to register. MOVE instructions 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: MOVE16,
MOVEM, MOVEP, MOVEQ, EXG, LEA, PEA, LINK, and UNLK. The MOVE16 instruction is
an MC68040 extension to the M68000 instruction set.
The FMOVE instructions move operands into, out of, and between floating-point data
registers. FMOVE also moves operands to and from the floating-point control register
(FPCR), floating-point status register (FPSR), and floating-point instruction address register
(FPIAR). For operands moved into a floating-point data register, FSMOVE and FDMOVE
explicitly select single- and double-precision rounding of the result, respectively. FMOVEM
moves any combination of either floating-point data registers or floating-point control
registers. Table 3-2 lists the general format of these integer and floating-point data
movement instructions.
