3.2 ESELSBRÜCKE: SPI Interface, I/Os, and Test Points
The multi-pin connector ESELSBRÜCKE is used to connect STARTRAMPE and TMC5130-EVAL. Pin connections
include the SPI interface, supply voltages, and IOs like driver enable (DRV_ENN), position compare (PP),
interrupts (INT), and status flags. ESELSBRÜCKE offers test points for several measurements.
