Table 2-4: Reset Connection
By default, the external reset is enabled and set to immediate reset while 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 (DTR/DTRx) is set, the UART RESET jumper (JP4) and the according DTR/RTS
(JP3 and JP5) 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.
