Symbol Description
:3/:8/:16/:24 3-, 8-, 16-, or 24-bit length
Note: * General registers include 8-bit registers (R0H to R7H, R0L to R7L), 16-bit registers (R0
to R7, E0 to E7), and 32-bit registers/address registers (ER0 to ER7).
Table 2.2 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 B (EAs) → Rd, Cannot be used in this LSI.
MOVTPE B Rs → (EAs) 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.
Note: * Refers to the operand size.
B: Byte
W: Word
L: Longword
