在调试clb_ex11_interrupt_tag例程，发现无法进入中断，详细如下：

这段代码主函数是一个while空循环，只是CLB模块内有个计数器在两个比较匹配值时会触发中断，理论上就会进入ISR。编译、下载、调试、运行都不报错，但就是不进入ISR，得到不预期功能。

期待官方能解答一下。

F28377D上没有CLB：

拜托你们用关键词”28377D CLB“搜一下这个论坛里有多少个相关的问题了，很多人都被sysconfig带坑里去了，你们还说因为sysconfig处于初期阶段，最早的问题提出都是三四年前了，你们工程师竟然还答复说因为别人的硬件有问题（(+) TMS320F28377D: ePWM using CLB Tool - C2000 microcontrollers forum - C2000︎ microcontrollers - TI E2E support forums），你们为啥还不能在ccs/sysconfig里把28377D不支持的功能屏蔽掉啊！
