Function of the board
The board is controlled by the NHE board. The keyboard is evaluated with
a key matrix and the LEDs are activated directly.
The LEDs are always switched on when they receive acknowledgment
from the corresponding component that the function has been activated.
There is no acoustic feedback when the key is activated.
