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.
