drv8301 revd电路原理图的疑问

那就是去掉这些没有配置的接口也没有影响？我要怎么知道是哪一种电流调理方式？高速时运行电流重构算法用的是哪一种？

下面的ADC端口在哪里定义的？怎么没有找到？把IA_FB、IB_FB、IC_FB切断后，下面的函数不发挥作用了吧？为什么对电机的性能没有影响？

非常感谢您的耐心回答，我把IA-FB,IB-FB,IC-FB强行在硬件电路板上去掉，电机的运行性能和没有去掉的时候一样，这样应该不会留下什么后遗症吧？

在void HAL_cal(HAL_Handle handle)有使用IC_FB进行HAL_AdcOffsetSelfCal(handle),IB_FB进行HAL_OscTempComp(handle)校准，直接去掉硬件接口，确认没有影响吗？

void HAL_cal(HAL_Handle handle)
{
  HAL_Obj *obj = (HAL_Obj *)handle;

  // enable the ADC clock
  CLK_enableAdcClock(obj->clkHandle);

  // Run the Device_cal() function
  // This function copies the ADC and oscillator calibration values from TI reserved
  // OTP into the appropriate trim registers
  // This boot ROM automatically calls this function to calibrate the interal
  // oscillators and ADC with device specific calibration data.
  // If the boot ROM is bypassed by Code Composer Studio during the development process,
  // then the calibration must be initialized by the application
  ENABLE_PROTECTED_REGISTER_WRITE_MODE;
  (*Device_cal)();
  DISABLE_PROTECTED_REGISTER_WRITE_MODE;

  // run offsets calibration in user's memory
  HAL_AdcOffsetSelfCal(handle);

  // run oscillator compensation
  HAL_OscTempComp(handle);

  // disable the ADC clock
  CLK_disableAdcClock(obj->clkHandle);

  return;
} // end of HAL_cal() function

// set SOC0 channel select to ADCINA5
  ADC_setSocChanNumber(obj->adcHandle, ADC_SocNumber_0, ADC_SocChanNumber_A5);

 //Select channel B5 for all SOC
  HAL_AdcCalChanSelect(handle, ADC_SocChanNumber_B5);
