MOVE.L
Move Long (AGU)
MOVE.L
Description
These operations move a signed long word (32-bit data) from memory to a register, or from a register to
memory. Absolute addresses, offsets, and address register values must be long word-aligned (the address
must be a multiple of 4). The programmer should ensure that the effective address resides on a long word
boundary.
