If a direct clock source is used, it must be connected to OSCIN pin and OSCOUT pin
supplies the inverted OSCIN signal (see Figure 10).
Figure 10.
OSCIN and OSCOUT pins configurations
Note:
When OSCIN is UNUSED, it should be connected to ground.
When OSCOUT is UNUSED it should be left floating.

Overcurrent detection
When the current in any of the power MOSFETs exceeds a programmed overcurrent
threshold, STATUS register OCD flag is forced low until the overcurrent event is expired and
a GetStatus command is sent to the IC (see paragraphs 9.1.22 and 9.1.17). Overcurrent
event expires when all the power MOSFET currents fall below the programmed overcurrent
threshold.
