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.

regulator output voltage
The UVLOVAL bit sets the UVLO protection thresholds.
The EN_VSCOMP bit sets if the motor supply voltage compensation is enabled or not.
