DRV8320: Negative current spike at disable on INL

Part Number: DRV8320

Hi TI support team,

We are using a DRV8320 in 3PWM mode to control our brushless motor. We use the INLx pins to disable all the PWM outputs in a single row (DRV_INL net on schematic). We are observing a big negative current when pulling low all the 3 INLx pins.

Here is the scope behavior.

How is it possible ? Can we change anything to avoid any negative current as presented above ? It is very annoying for us

Thanks in advance
