DRV8323R: drv8323RS Missing decoupling in DVDD

I am using drv8323rs partnumber. Due to a design mistake, I did not include the DVDD's decoupling capacitor in the artwork. At this time, when operating the motor, an unknown offset was detected in the motor current depending on the power on/off. This should not be related to the DVDD, but it is shown in the experimental results. I'm curious why the presence or absence of a DVDD decoupling capacitor makes such a difference.
