57 / 73 page  L6482 Programming manual Doc ID 023768 Rev 2 57/73 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 VCC regulator output voltage. Table 38. Programmable VCC 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. Table 37.
