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 is remaining to be read, it will not be possible to reread that whole block.
The check bits (10 bits) are not output.
The data valid / invalid decision is made by referencing the error information flag (E0 to E2) but the offset word
detection flag (OWD) must not be referred to.
When the first leading bits are not “1010”, the read in data is invalid, and the read operation is cancelled.
