Some devices further have the possibility to disable the RESET pin by clearing the RSTDISBL Fuse. When the RESET pin is disabled it can be used as an IO pin by the application. To be able to enter Programming mode when the RESET pin is disabled the RESET pin has to be pulled “very high” – to 12V. If

another criteria for a successful enhancement of the resolution is that the input signal has to vary when sampled. This may look like a contradiction, but in this case variation means just a few LSB. The variation should be seen as the noise-component of the signal. When oversampling a signal, there should

Button-Button Spacing When button pitch is small and buttons are very close together, there may be interaction between buttons. Capacitive elements should be tied to ground when not active to minimize this interaction and decrease
