| - | The description of the debounce timer is found at the end of section 26.1. For this design, however, you will be required to wait precisely 5ms instead of whatever the maximum value for your timer is. At 5ms your timer should assert "timerDone". Your counter should be cleared when clrTimer is asserted by the state machine. By the way, if you have a parameterized counter from a previous lab, go ahead and use it - no need to re-invent the wheel. If not, you may choose to create a counter module parameterized for both maximum count value as well as bit-width (you will be needing such a counter in essentially every lab you complete moving forward). | + | The description of the debounce timer is found at the end of section 26.1.

Explain how you implemented the state machine and how the state machine should behave when it receives a noisy input.\\ \\ | **Exercise 1 Pass-off:** Show a TA your debounce module.
