The pushbutton on the FPGA module should not be used.
Explanation: The pushbutton (located on the underside of the module) was intended to provide a hardware reset to the MISE.
Due to a board layout error its FPGA pin is allocated to an output signal. Pressing the pushbutton will short this signal to ground,
potentially damaging the FPGA.
The reset button in the Model I keyboard unit provides a hardware reset to MISE.
