Is it okay to switch the mode pin (float or GVDD) on the fly, while the DRV8770 is running the motor?

Thanks!

Hi Lenio,

It is okay to change the MODE pin on the fly but it is not recommended to change the MODE while outputs are active. The control logic change may cause unwanted behavior at the output terminals.
