(*) (refer to: Specification of the radio data system EN50067

of CENELEC, ANNEX B). When bits 4...0 of the syndrome

register are all zero a possible error burst is stored in this

bits. With the help of the correction pattern(bits 9..5 of the

syndrome register), the type of error can be measured in or-

der to classify the reliability of the correction.

It is an information about a correct syndrome after recep-

tion resp. after an error correction routine.

1: a correct syndrome was detected.

0: the syndrome was wrong. The current RDS data cannot

be used.

It is an information about error correction.

1: an error correction was made.

0: the actual RDS block is detected as error free.
