correlation threshold can be set to 15/16,16/16, or 30/32 bits match. The sync word canbe further qualified using the preamble qualityindicator mechanism described below and/or acarrier sense condition. The sync word isconfigured through the SYNC1 and SYNC0registers.In order to make false detections of syncwords less likely, a mechanism calledpreamble quality indication (PQI) can be usedto qualify the sync word. A threshold value forthe preamble quality must be exceeded inorder for a detected sync word to be accepted.See Section 17.2 on page 36 for more details
