←M(S)

Restores the contents of the stack on the index register Y.

M(S)

←A, B, X···

Saves the registers among accumulator, index register, direct

page register, data bank register, program bank register,

or processor status register, specified by the bit pattern of

the second byte of the instruction into the stack.

Restores the contents of the stack to the registers among

accumulator, index register, direct page register, data bank

pattern of the second byte of the instruction.

(Note 13)

Rotates the contents of the accumulator A, n bits to the

left.

ROL

(Note 1)

Links the accumulator or the memory to C flag, and rotates

result to the left by 1 bit.

m=0

→ C → b15 ··· b0 →

→ C → b7 ··· b0 →

ROR

(Note 1)

Links the accumulator or the memory to C flag, and rotates

result to the right by 1 bit.
