怎样擦出nv_store保存在协调器的列表

启用nv_store的预编译后，会保存链接信息。但发现连过的设备多了以后，有新节点再也加不进去了（加入过的节点已经不在网络了），请问擦出这个存储列表的函数是什么呀，有没有更新列表的操作函数呀？

application wants to delete the stored NV information It just needs to set the ZCD_NV_STARTUP_OPTION as explained below and do a reset. 

"If the application would like to force a "new" join, the application should set the ZCD_STARTOPT_DEFAULT_NETWORK_STATE bit in the ZCD_NV_STARTUP_OPTION NV item before calling this function. "New" join means to not restore the network state of the device. Use zgWriteStartupOptions() to set these options 

你把无关紧要的节点关联信息删除了就可以了，参考如下：
