The OC_SD bit sets if an overcurrent event causes or not the bridges to turn off; the OCD
flag in the status register is forced low anyway:
The VCCVAL bit sets the internal V
CC
regulator output voltage.

CC
regulator output voltage
The UVLOVAL bit sets the UVLO protection thresholds.
The EN_TQREG bit sets if the torque regulation is performed through ADCIN voltage
(external) or the TVAL_HOLD, TVAL_ACC, TVAL_DEC and TVAL_RUN registers (internal).
The TSW parameter is used by the current control system and it sets the target switching
period.
