CCB Output Data Format

• Each block of output data consists of 32 bits (4 bytes), of which 2 bytes are RDS data and 2 bytes are flag data.

• Any number of 32-bit output data blocks can be output consecutively.

• When there is no data that can be read out in the internal memory, the system outputs blocks of all-zero data

consecutively.

• If data readout is interrupted, the next read operation starts with the 32-bit data block whose readout was interrupted.

However, if only the last bit remains to be read, it will not be possible to reread that whole block.

• The check bits (10 bits) are not output.

• To judge whether or not the data is valid, refer to the error information flags E0 to E2, but the offset word detection

flags (OWD) should never be reffered to.

• If the first four-bits are not “1010”, since the readout data is invalid, readout operation must be halted.

1. Offset word detection flag (1 bit): OWD

2. Offset word information flag (3 bits): B0 to B2
