DRV8825: The actual current peak does not match the set current value after stopping STEP signal

Tool/software:

hi,

After the motor is spinning normally, the customer stops the motor by stopping a pulse signal to the step pin. The current through the motor 2 phases are tested and the current through one of the phase  is much larger than the set maximum of 300 mA. Is this normal?

Test condition: After the motor is spinning normally, the customer stops the motor by stopping a pulse signal to the step pin.

Decay mode: Mixed decay; Microstep:  1/32; Without load with motor

the waveforms of phase current following out AOUT/BOUT are listed in attached.
