Figure 9.
Here in the "master" position, place it in the alternative position on the board used as slave.

Figure 10. Awake input
This jumper must be closed on the master board, in this way the nAWAKE pin can be driven
by the EVAL_IBU-STR7 board.

Figure 11. Stepper current sense resistor value
You can choose a different sense resistor value according to your application requirements.
Bridge 3 and 4 have three resistors available connected in parallel with value: 1 Ω, 2.2 Ω and
3.9 Ω.. By default these jumpers are all closed, and the resulting sense resistor is about 0.6
Ω.
