MOVE.L

MOVE.L (a32),DR

MOVE.L DR,(a32)

Moves a 32-bit long word between a data or address register and a memory address pointed to by a 32-bit absolute address.

MOVE.L (a16),C4

MOVE.L C4,(a16)

Moves a 32-bit long word between a general register and a memory address pointed to by a 16-bit unsigned absolute address.

MOVE.L (Rn+u3),DR

MOVE.L DR,(Rn+u3)

Moves a 32-bit long word between a data or address register and a memory address pointed to by an address register plus a 3-bit unsigned offset that is preshifted right by 2 bits. The offset u3, defined by the programmer, must be a multiple of four from 0:28. It is encoded by the assembler with 3 bits, thus creating a 3-bit offset, which is coded in the instruction. The core, when decoding the instruction, post shifts left the 3-bit offset to reconstruct the real offset. This feature enables condensed code size when short immediates are needed.

MOVE.L (Rn+s15),DR

MOVE.L DR,(Rn+s15)

Moves a 32-bit long word between a data or address register and a memory address pointed to by an address register plus a 15-bit signed offset.

MOVE.L (Rn+Rr),DR

MOVE.L DR,(Rn+Rr)

Moves a 32-bit long word between a data or address register and a memory address pointed to by an address register plus the contents of a second address register as an offset. The second address register (Rr) is shifted left by 2 bits prior to being added. The modifier mode of this instruction is determined by Rn in MCTL. Rr is limited to R0–R7.

MOVE.L (EA),DR

MOVE.L DR,(EA)

Moves a 32-bit long word between a data or address register and a memory address pointed to by an address register with optional offset or post-increment.

MOVE.L (Rn),C3

MOVE.L C3,(Rn)

Moves a 32-bit long word between a control, offset, or modifier register and a memory address pointed to by an address register.

MOVE.L (SP–u6),DR

MOVE.L DR,(SP–u6)

Moves a 32-bit long word between a data or address register and a memory address pointed to by the active stack pointer minus a 6-bit unsigned offset.
