3.13 Reset-Generation (JP: 3, 4, 5, 7, 24, 35)
In addition to the internal Power-On reset, the microcontroller can be reset by an external
reset circuit (Voltage Monitor) and also by a RS232 interface.
JP3, JP5 As well the DTR-line as the RTS-Line of UART”A” or UART”B” can be used
JP4
JP7
JP24
JP35
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.

Jumper
reset is generated to avoid accidental resets.
to generate a system reset.
This jumper selects whether the DTR/RTS line from UART”A” or UART”B”
will generate a system reset.
This solder jumper selects between normal (immediate) reset and delayed reset.
In delayed reset mode, the reset button has to be held down for 2 sec before a
Open this jumper if no external Reset shall be generated.
In this case only the internal reset is active (e.g.: power-on)
The signal on the DTR/RTS line can be negated with this jumper.
Remove the jumper in order to disable the RS232 reset circuit.
