|

* Notes on led-identify and id-button:
|
||||
* - A physical button is connected to id-button which
|
||||
* triggers the clock on a D flip-flop. The /Q output of the
|
||||
* flip-flop drives its D input.
|
||||
* - The flip-flop's Q output drives led-identify which is
|
||||
* connected to LEDs.
|
||||
* - With that, every button press toggles the LED between on and off.
|
||||
*
|
||||
* Notes on power-, reset- and nmi- button and control:
|
||||
* - The -button signals can be used to monitor physical buttons.
|
||||
* - The -control signals can be used to actuate the specific
|
||||
* operation.
|
||||
* - In hardware, the -button signals are connected to the -control
|
||||
* signals through drivers with the -control signals being
|
||||
* protected through diodes.
