The TMC5160-EVAL user manual is unavailable. The TMC5130-EVAL user manual (TMC5130-EVAL User Manual) can be used as replacement for the TMC5160-EVAL user manual because setting up connections and direct mode running process are very similar.
To explore additional features of the TMC5160, it is recommended to check the datasheet of the TMC5160 : TMC5160/A Datasheet.
