InstaSpin-FOC历程中初始化了电流滤波器，但没有使用是什么情况

最近学习TI的InstaSpin-FOC，看见里面初始化了滤波器参数，但程序没用到滤波器过滤电流。是我没找到操作代码还是程序中就没用。

下面是电流读取代码到clarke部分；下面是Lab 1C 。

HHAL_readAdcData中只从ADC寄存器中读取了滤波器ADC值，并进行了简单的比例和IQ转化，没有滤波；
CLARKE_run中直接进行clarke变化，也没有滤波。
剩下代码中都没有关于adc的操作。
既然InstaSPIN 初始化了滤波器参数，为什么不用呢?
TI demo板有一个RC 低通滤波器，截止频率在450KHZ，远不能滤除噪声。必定还要其他滤波才能行。但一直没找到。
谁能帮我解答一下。
