By default, the external reset is enabled and set to immediate reset, the reset by UART is
disabled.
Note:
While a reset signal is asserted the red Reset-LED D10 is lit.
During normal operation, this LED should be off!
If JP51(DTR sel) is set, one of the RST jumpers (JP60, 70, 80, 90) and the according
DTR/RTS jumper 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 and JP51.
