JP38 (RST MCU)
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 JP13 (DTR/DTRx) is set, one of the RST jumpers (JP15, 16, 42, 43) 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.
