What is the working principle of TS3A226AE IC automatic switching earphone mode?What determines switching?

请问TS3A226AE这款IC，自动切换耳机模式的工作原理是什么？是通过什么来判断切换的？

    您好，是根据耳机的类型进行自主切换，比如3极或4级的配件插到移动设备中的方法是不一样的，，您看下面真值表中Accessory Congifuration的连接方式， 换句话说，根据这种配置方式的不同来自主切换。

    The autonomous  detection feature allows end users to plug in accessories with different audio pole configurations  into the mobile device and have them operate properly。
