Chapter 6 Debug and Programming interface
For connection of the microcontroller debug and flash programming tools, the
connector CN19 is provided.
The signal connection of the connector CN19 is shown in the picture below:

* In case the FLMD1 signal must be controlled by the debug/programming tool,
the pin header JP11 must be closed.
The ‘Dbg_Voltage’ (on CN19 pin 8) can be monitored by the debug and flash
programming tools. Therefore it is possible to select either Voltage1 or the
Voltage2 by pin header JP10:
