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 28 below.

From
- FifoLevel interrupt is updated only after a read or write operation on the FIFO. Thus the interrupt cannot be
dynamically updated by only changing the FifoThreshold parameter
- FifoLevel interrupt is valid as long as FifoFull does not occur. An empty FIFO will restore its normal operation
