FM radio + RDS
If for some reason a valid B block was not received then the next valid A or C’ block is
decoded and the DAVFLG set. The BP and BL registers record the A block history.
When the decoder is synchronized, each decoded block will set the DAVFLG (assuming it
was reset by a read action) and generate an interrupt.
10.3 DAV-C reduced processing mode
The DAV-C processing mode is very similar to DAV-A mode with the main exception that a
data flag is set only after two new blocks are received. Hence the update rate is reduced
by half.
When the number of blocks detected in the order: ‘bad’ ‘bad’ ‘good’ is 2, synchronization is
achieved if another good block followed by either 0, 1 or 2 bad blocks and another good block
are then received. If the order is 3 bad blocks, no synchronization is achieved and the counters
are reset.
