1 votes 1 votes The RET instruction needs 3 machine cycles. One to fetch and decode the instruction (4 T states), and two more machine cycles (that is, 2*3 = 6 T states) to read two bytes from the stack hari_krish answered Mar 4, 2018 hari_krish comment Share Follow See all 0 reply Please log in or register to add a comment.
