4.3 P17_0 (JP50)
Depending on the MCU and the operation mode of the MCU the connection between pin 22
and DIP switch is closed.
In case of using the debug interface with a MB966xx microcontroller it is recommended to
open the jumper JP50, as this pin can be used as GPIO. Furthermore the level of the mode
pin MD_temp (P17_0) has no influence in RUN mode as well as in Serial Programming
mode.
Due to the mode pin settings of the former MB963xx device mode pin MD1 must be closed
to external pull up resistor and to the DIP switch.

4.4 Debug (JP: 51A, 51B)
The jumpers JP51A and JP51B, parallel to each other, connect the DIP switch for
configuration of pin 17. That pin corresponds to the MB96600 mode pin Debug I/F and the
former MD0 pin of MB96300 super series.
In case of a MB963xx MCU the jumper JP51A/B must be closed, in order to get the MCU
into serial programming mode for flashing the microcontroller. For detailed description about
the operation modi see chapter 4.2Error! Reference source not found..
In case of a MB966xx device the MCU can be programmed by the Softune Workbench via
the debug interface. As there are strict layout design rules for the debug signal line the
jumper JP51A/B ought to be open.
JP51A solder jumper connects DIP switch and mode pin pin 17 to change mode
configuration
JP51B normal jumper: same functionality as JP51A as both jumpers are in parallel
