Slow decay mode

WebbIn 'slow decay' mode, the current flows through the two bottom FETs, which are on, and the motor voltage is near zero. The only voltage available to reduce current in the inductance is the voltage drop on the motor resistance and the FET resistance. Webb1. Because not matter it is fast decay or slow decay, the winding current will eventually drop to zero. Then how could I prove it is fast decay or slow decay by using the "Stop" button? 2. I found there is a driven current waveform in the DRV8833C datasheet. Do you know how to test it with DRV8833C EVM? 3.
