Note 2:
While a reset signal is asserted the red Reset-LED D1
is lit.
During normal operation, this LED should be off!
If JP33 (Polarity) is set, JP72 and either JP28 or JP50
or JP71 have to be set, too.
If the reset LED is steadily on, check the power supply
input voltage and the settings for the reset-generation
by UART.
