  • To better understand the use of the CPU flags, it might help to see some examples of their use. In this episode, learn how the flags are set after a simple integer addition and how the zero and sign flags support conditional execution of our code.
    Take aways: At the completion of this lesson, each student should be able to:
    • determine the settings of the zero, the sign, the overflow, the carry, the half carry, and the parity flags based on the results of an integer addition and
    • show how the zero flag and the sign flag can be used to control program flow.

    After a long time of thinking how you could write on the glass without making the letters and numbers appears inversed I figured out you just mirror the video. Brilliant!
