​Vset: Set voltage. In LIN mode, The regulation voltage​ set by LIN RX frame. //设定调节电压。LIN调节模式下，Vset为LIN协议RX帧设定的调节电压值；默认模式下，Vset为OTP中写入的默认调节电压。 Vreg：Regulation voltage. the actual value that device regulate. During Thermal compensation or LIN timeout, Vreg is not equal to Vset. //调节电压。芯片实际工作中调节的目标电压值。温度补偿或者LIN超时，实际的调节电压Vreg会不等于Vset。  

If you want to use MC33AR6000 to replace MC33TC80310 in a mature platform, should pay attention to some small difference on actions and diagnoses. See attachment for details.

In pre excitation mode 2, you can have any duty cycle between pre exc value and 100% depending on battery and Vset voltage. On some alternators, with high duty cycles, the switching of excitation causes so much noise through the phase that this noise can be interpreted as valid phase signal. Thus, the device can go to regulation. To avoid that, we added the ability to deglitch the phase input only in pre excitation mode 2 to be sure that the signal we have are real phase signals. Depending on the duration of the noise our customer can see during pre excitation mode2, they can set the value of deglitcher. If they don't use pre excitation mode2, this value is "don't care".
