Data Transfer Instructions

Instruction

Size*

Function

MOV

B/W/L

(EAs)

→ Rd, Rs → (EAd)

Moves data between two general registers or between a general register

and memory, or moves immediate data to a general register.

MOVFPE

Cannot be used in this LSI.

MOVTPE

Cannot be used in this LSI.

POP

W/L

@SP+

→ Rn

Pops a general register from the stack. POP.W Rn is identical to

MOV.W @SP+, Rn. POP.L ERn is identical to MOV.L @SP+, ERn

PUSH

W/L

→ @-SP

Pushes a general register onto the stack. PUSH.W Rn is identical to

MOV.W Rn, @-SP. PUSH.L ERn is identical to MOV.L ERn, @-SP.

LDM*

@SP+

→ Rn (register list)

Pops two or more general registers from the stack.

STM*

Rn (register list)

→ @-SP

Pushes two or more general registers onto the stack.

Notes: 1. Size refers to the operand size.

B: Byte

W: Word

L: Longword

2. ER7 is not used as the register that can be saved (STM)/restored (LDM) when using

STM/LDM instruction, because ER7 is the stack pointer.
