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. Refers to the operand size.
B: Byte
W: Word
L: Longword
2. Only register ER0 to ER6 should be used when using the STM/LDM instruction.
