function IntEventCombineInit
*
* \brief This API removes all system events from the ECM, assigns
* the event ISRs to a default handler, registers the ECM
* ISR to the corresponding CPU interrupt, maps the ECM
* system event to the corresponding CPU interrupt, and enables
* the CPU interrupt.

这个ECM是什么，有什么作用啊？

ECM是指Event Combiner，是中断控制器里的一个模块，见下面的文档第160页7.2.2 Event Combiner。http://www.ti.com/lit/ug/sprufk5a/sprufk5a.pdf
