Data Movement

  The most basic instruction for moving data is the MOVE instruction. It has a number of variants, such as MOVEA for moving data into an address register.

Other useful data movement instructions include LEA and PEA.

• LEA $0010FFFF,A5 - loads the address $0010FFFF into A5.

• LEA $12(A0,D4.L),A5 - loads the address $12 + (A0) + (D4) into A5.

• PEA SUM - pushes the effective address of SUM onto the stack, where SUM is a label.
