Table 2.3 Data Transfer Instructions
Instruction Size*¹ 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
B
Cannot be used in this LSI.
MOVTPE
B
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
Rn → @-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*²
L
@SP+ → Rn (register list)
Pops two or more general registers from the stack.
STM*²
L
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.
