对zlight-router一段code无法理解

灯作为服务器，接受命令，使用zclGeneral_HdlInSpecificCommands处理相关命令，找到了我的命令

#ifdef ZCL_LEVEL_CTRL
    case ZCL_CLUSTER_ID_GEN_LEVEL_CONTROL:
      stat = zclGeneral_ProcessInLevelControl( pInMsg, pCBs );
      break;
#endif

问题就是在zclGeneral_ProcessInLevelControl( pInMsg, pCBs );函数里

问题一：下面代码的pData[1]是指什么。pData是一个指针，pData 只是定义了uint8 *pData

cmd.moveMode = pInMsg->pData[0];
cmd.rate = pInMsg->pData[1];
问题二：在回调函数zclLevel_StepCB里有个函数是

hwLight_ApplyUpdate( &zclLevel_CurrentLevel,
                       &zclLevel_CurrentLevel_256,
                       &zclLevel_StepLevel_256,
                       &zclLevel_LevelRemainingTime,
                       LEVEL_MIN, LEVEL_MAX, FALSE );

这函数具体是什么功能呢？

1，这个指的是rate，API函数里面是有说明的

/*********************************************************************

ZStatus_t zclGeneral_SendLevelControlMoveRequest( uint8 srcEP, afAddrType_t *dstAddr,
uint8 cmd, uint8 moveMode, uint8 rate,
uint8 disableDefaultRsp, uint8 seqNum )
{
uint8 buf[2];

buf[0] = moveMode;
buf[1] = rate;

return zcl_SendCommand( srcEP, dstAddr, ZCL_CLUSTER_ID_GEN_LEVEL_CONTROL,
cmd, TRUE, ZCL_FRAME_CLIENT_SERVER_DIR,
disableDefaultRsp, 0, seqNum, 2, buf );
}

2，计算处理PWM的输出，
