Reset
If the device needs to be shut down during operation the RESN pin can be pulled low. The RESN pin should be
held low until the current flowing in the solenoid decays to zero. If the device is restarted with current flowing in the
solenoid the auto zero function will enter the value as an offset, causing an error in the current control.
