Yep, it does.

ROL rotate left

ROR rotate right

ASL arithmetic shift left

LSR logic shift right

But for it to work for all 2-complement coded values we need to ensure that the MSB is copied back into itself to keep the value the same sign, which can be done with another shift.

; Divide a signed 16-bit value by 2

        LDA MEM+1    ;Load the MSB

        ASL A        ;Copy the sign bit into C

        ROR MEM+1    ;restore MSB

        ROR MEM+0    ;Rotate the LSB

It's a bunch of cycles but nothing compared to a generic division.
