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
