WDT[3:0] Selects the watchdog timeout interval.
Table 13. WATCHDOG TIMEOUT INTERVAL AS FUNCTION OF WDT[3:0]
CUR[4:0] Selects IMCmax peak. This is the peak or amplitude of the regulated current waveform in the motor coils.
16. Typical current amplitude at T
17. Reducing the current over different current ranges might trigger overcurrent detection, please refer to dedicated application note for solutions.
