Chapter 5 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 EVTOUT signal shall be used by the debug/programming tool, the
pin header JP11 must be closed.
The ‘Dbg_Voltage’ (on CN19 pin 8) is monitored or supplied by the debug and
flash programming tools. Therefore, it is necessary to select either Voltage1 (5V)
or the Voltage2 (3.3V) by pin header JP10:
