Digital Filter在CMPSS模块中的位置：

Digital Filter 实现的等效C代码如下:

//Equivalent C code of the filter implementation 
//is shown below:
if (FILTER_OUTPUT == 0) {
   
   
	if (Num_1s_in_SAMPWIN >= THRESH) {
   
   
		FILTER_OUTPUT = 1;
	}
}
else {
   
   
	if (Num_0s_in_SAMPWIN >= THRESH) {
   
   
		FILTER_OUTPUT = 0;
	}
}

Digital Filter 使用步骤：

1. Configure and enable the comparator for operation
2. Configure the digital filter parameters for operation
   • Set SAMPWIN for
