TLE9185x: How to enter in software development mode?
In order to enter in software development mode the INTN/TEST pin has to be externally pulled-down and an arbitrary SPI command has to be sent.
Doing that the software development mode is latched and the pull-down can be released. In case the TLE9185x shield is used the correspondent jumper needs to be set.
For more details refer to the "BLDC shield TLE9185QX/TLE9185QX V33 user guide".
