5.2.3. Sync Word Recognition

5.2.3.1. Overview

Sync word recognition (also called Pattern recognition) is activated by setting SyncOn in RegSyncConfig. The bit

synchronizer must also be activated in continuous mode (automatically done in Packet mode) .

The block behaves like a shift register; it continuously compares the incoming data with its internally programmed Sync

word and sets SyncAddressMatch when a match is detected. This is illustrated in Figure 24 below.
