TI中文支持网Part Number:TMS320F280049Other Parts Discussed in Thread:POWERSUITE, C2000WARE
1.在EPWM设置函数的闭环部分中，首先对于EPWM2模块的AQ动作进行了设置，将DCEVTFILT连接到T1,并设置了T1U和T1D动作事件。但随后又在TZ模块中将DCEVTFILT事件进行了设置，也同样设置了在事件到来时分别处于上升沿以及下降沿两种情况下EPWM的动作，为什么要这样做？
2.关于280049的TZ子模块，我找到的资料里并没有说明TZA或TZB可以结合TBCTR处于上升沿还是下降沿对EPWM的输出进行修正，为什么程序中结合了上升或下降沿？
3.最后又设置了TZA与TZB不动作，那之前设置的Advanced Trip Zone Action指的是其他什么吗，这个Advanced怎么理解。

Ben Qin：
你好，你使用的例程具体是哪一个？能否说明一下文件路径？

参考下TRM第18.11.4.2章节：

你好，此项目路径为C:\ti\c2000\C2000Ware_DigitalPower_SDK_4_04_00_00\powerSUITE\source\devkits\.meta\TIDM_02000。
我参考了这一章节的内容，似乎和我的问题关系不大，我的疑惑是此程序中既设置了TZ子模块响应事件，又同时在AQ子模块中也设置了相同的响应事件，我不清楚为何要这么做。

该路径下我不到该项目

能否指出具体在第几行？
? ? said:将DCEVTFILT连接到T1,并设置了T1U和T1D动作事件。但随后又在TZ模块中将DCEVTFILT事件进行了设置
你给的代码中我只看到了AQ模块有相关配置。
