TI中文支持网有几个问题想请教：
1、数据传输时，afAddrType_t 目标地址中的 endPoint ，端点，作用是什么，表示什么意思
// Fill out the endpoint description.
SampleApp_epDesc.endPoint = SAMPLEAPP_ENDPOINT;
SampleApp_epDesc.task_id = &SampleApp_TaskID;
SampleApp_epDesc.simpleDesc
= (SimpleDescriptionFormat_t *)&SampleApp_SimpleDesc;
SampleApp_epDesc.latencyReq = noLatencyReqs;
// Register the endpoint description with the AF
afRegister( &SampleApp_epDesc );
2、这里注册的描述是什么，为什么也是同一个值SAMPLEAPP_ENDPOINT
3、传输数据时这个endPoint是否重要？如果是，网络中的协调器、终端节点又该如何设定值
