Figure 7. Battery stack connection

6.2 Jumper connection

One hand-soldered jumper (JP11) on the EVB is used to set the GPIO0 pin input. In

position 1-2 (default), the NTC (NTC0) is connected to GPIO0 pin of the MC33772B.

This input can be used as analog input. If the jumper is placed in position 2-3, the GPIO0

can be used as fault input for fault daisy chain function (need to populate R26 with a10 k

resistor).
