10.1 Selection between I
9.6 Error detection and reporting
9.7 RDS data - reading from registers
The TEA5766UK must report information on the number of errors corrected in the last and
previously decoded blocks. This is reported in the ELB[1:0] and EPB[1:0] fields as shown
in
During synchronization search the error correction is disabled for detection of the first
block and is enabled for processing of the second block according to the mode set by the
SYM[1:0] bits as described in
To read RDS data the microprocessor must read byte 12R to byte 19R. All 8 bytes must
be read to reset the status bytes byte 12R and byte 13R, i.e. effectively the status bits can
be updated by the decoder after reading the last bit of byte 19R. The DOVL bit is cleared
after reading the last bit of byte 19R and the status of the SYNC bit does not depend on
reading the register; the SYNC bit tells if the decoder is synchronized or not. When
starting a read action from byte 12R, the decoder blocks update from the RDS bytes until
byte 19R has been read. RDS byte 12R to byte 19R must be read in one read action.
