How does the ICU module of the EB tresos tool configure an external input pin interrupt？
在TDA4VM平台的EB tresos工具中，只看到了中断的回掉函数，没有发现有地方配置外部中断的引脚与中断绑定。
另外MaxChannel最大只有3，如果我使用大量的外部输入引脚的中断，应该如何操作？
In the EB tresos tool for the TDA4VM platform, only the abort callback function is seen, and there is no place to configure the pins and interrupt bindings for external interrupts.
Also IcuMaxChannel is 3, what should I do if I use a lot of external input pin interrupts?
