关于vlfft例程中Hwi的使用问题，感谢大神指点

cfgScript代码如下：

var Log = xdc.useModule ("xdc.runtime.Log");
var Hwi = xdc.useModule('ti.sysbios.hal.Hwi');
var Semaphore = xdc.useModule('ti.sysbios.knl.Semaphore');
var Cache = xdc.useModule('ti.sysbios.hal.Cache');
var CpIntc = xdc.useModule('ti.sysbios.family.c66.tci66xx.CpIntc');

ECM.eventGroupHwiNum[0] = 7;
ECM.eventGroupHwiNum[1] = 8;
ECM.eventGroupHwiNum[2] = 9;
