A simple digital watch has a display and two buttons to set it, the A button and the B button. The watch has two modes of operation, display time, set time in the display time mode, the watch displays hours and minutes, separated by a flashing colon.
The set time mode has two sub-modes, set hours, set minutes. The bottom A selects modes. Each time it pressed, the mode advance in the sequence: display set hours, set minutes, display etc. Within the sub-modes the button B advances the hour or minutes once each time it is pressed. Buttons must be released before they can generate another event. Prepare a state diagram of the watch.
