Function
(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.
Cannot be used in this LSI.
Cannot be used in this LSI.
@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.
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.
@SP+ → Rn (register list)
Pops two or more general registers from the stack.
Rn (register list) → @–SP
Pushes two or more general registers onto the stack.
