Pushbuttons
The functionality of all four pushbuttons S1 to S4 is fully under control of the application software.
All pushbuttons are active at log. high level. To provide log. low level in the inactive state, the pushbutton pins have on-board
pull-down resistors.
The pushbuttons have no hardware protection against contact bouncing when pressed and released. The protection should
be ensured in software.
Arrangement:
