... The action of the TEA5766UK depends on the status of the LSYNCMSK bit in this is set then the loss of synchronization causes the LSYNCFL to go logic 1 and a hardware interrupt is generated.

Page 20
... NXP Semiconductors If the LSYNCMSK bit is logic 0 and synchronization is lost the TEA5766UK automatically starts a new synchronization search. It will not generate a hardware interrupt. The host processor can wait until the RDS decoder is synchronized again; this will be indicated by the DAVFLG and the SYNC status bit (this requires the DAVMSK being set). ...

The TEA5766UK will now automatically initiate a new synchronization search. Each time when a good block is decoded the GBC value is incremented. When the GBC value is equal to the GBL value both counters (BBC and GBC), are set to 0 and a new count starts ...

... Blocking DAVFLG: at end of reading byte 15R or byte 17R (DAV-A, B/C) DAVFLG is forced to zero. Only after reading byte 19R DAVFLG is released again. If synchronous reading is performed using TEA5766UK generated interrupts, this problem does not occur. To prevent undefined situations, byte 12R to byte 19R should always be read in one action immediately after each other. ...
