DRV8323: Auto offset Calibration

Part Number:DRV8323

Hi,

The DRV8323/DRV8323R devices can perform an automatic offset calibration through the SPI registers or CAL pin.

I want to use the calibration through the SPI register. Which state of the pin CAL ? Not connect, tied to GND, tied to 3.3V ?

Thanks,

Mikaël
