Default: JP24 is closed; JP3, JP4, JP5 and JP35 are open
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 D14 is lit.
During normal operation, this LED should be off!
If JP35 (Polarity) is set, JP4 and either JP3 or JP5 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.
