MOVE.L
Instruction Fields:
Freescale Semiconductor
Notes: • The absolute address operand X:xxxx is specified as a word address.
Operation
MOVE.L
• Pointer Rn is a word pointer.
• Offsets xx, xxxx, and xxxxxx are word offsets.
• N offsets are long offsets.
• RRR pointers must be even.
• SP pointers must be odd.
• Immediate offsets must be even.
• Absolute addresses must be even.
• Offset N can be even or odd since it is a long offset that will be shifted left by 1.
