6.2 (6) Revise the state diagram from Exercise 5.2 to provide for more rapid setting of the time by pressing and holding the B button. If the B button is pressed and held for more than 5 seconds in set time mode, the hours or minutes (depending on the submode) increment once every 1/2 second. (Instructor's note: You may want to give the students a copy of our answer to Exercise 5.2 as the basis for this exercise.) 5.2 In Figure A5.2 the event A refers to pressing the A button. In this diagram, releasing the button is unimportant and is not shown (although you must obviously release the button before you can press it again). Note that a new button event cannot be generated while any button is pressed. You can consider this a constraint on the input events themselves and need not show it in the state diagram (although it would not be wrong to do so).
