关于MBR接近调整如何确定手指阈值？

你好
以下是MBR设计指南说明（P.78）

6。设置手指阈值等于接近正阈值。这需要确定ALP滤波器的响应。
事业单位
哪个参数指的是这个“手指门槛”？
这是“接近触摸阈值”吗？
或者这是“接近阈值”？
“接近阈值”范围从31到200。
“接近触摸阈值”范围从62到65000。
如果接近正阈值低于31或62，则不能将手指阈值设置为接近正阈的相同值。
在这种情况下，我们应该如何确定手指阈值？
如果手指阈值和接近正阈值不是相同的值，ALP滤波器将不能正常工作吗？
MBR在表6～6中描述了“接近触摸阈值”。
事业单位
“接近触摸阈值”是“差分计数的80%（当接近传感器被触摸时）”。
事业单位
如果“接近触摸阈值”必须与启用ALP滤波器的接近正阈值相同，那么我认为下面两个描述（A，B）相互矛盾。
（当手指阈值的一个点“接近触摸阈值”）。
我该怎么想呢？
当使用ALP过滤器时，我们应该只考虑一个案例吗？

最好的问候。

  Hello

Below is MBR Design Guide description(P.87)
=> http://www.cypress.com/file/46366/download

6. Set the finger threshold as equal to the proximity positive threshold. This is required to determine the response of the ALP filter


Which parameter refers to this “finger threshold”?
Is this “Proximity Touch Threshold”?
Or is this “Proximity Threshold”?

“Proximity Threshold” range is from 31 to 200.
“Proximity Touch Threshold” range is from 62 to 65000.

If proximity positive threshold is below is 31 or 62, finger threshold can not be set to the same value as proximity positive threshold.
In this case how should we decide finger threshold?

If finger threshold and proximity positive threshold are not the same value, will ALP filter not operate properly?


And MBR describes about “Proximity Touch Threshold” at Table 6-6.

“Proximity Touch Threshold” is “80% of Difference count (when proximity sensor is touched)”.


If “Proximity Touch Threshold” has to be the same value as proximity positive threshold at ALP filter enabled, I think the following two descriptions(A, B) contradict each other.
(when finger threshold  of A points “Proximity Touch Threshold”.)
How do I think about it?
When using ALP filter, should we consider only A case?

A. Set the finger threshold as equal to the proximity positive threshold. This is required to determine the response of the ALP filter
B. “Proximity Touch Threshold” is “80% of Difference count (when proximity sensor is touched)”.
