L6470
The OC_SD bit sets if an overcurrent event causes or not the bridges to turn-off; the OCD
flag in status register is forced low anyway:
Table 24.
The POW_SR bits set the slew rate value of power bridge output:
Table 25.
1. See S
The EN_VSCOMP bit sets if the motor supply voltage compensation is enabled or not.
Table 26.
The F_PWM_INT bits set the integer division factor of PWM frequency generation.
