Notes on Output Data Selection During Tuning (Provided for reference purposes.)
A tuning system is required in an FM multiplex broadcast reception system. However, applications must perform the
following processing if it is unacceptable for the IC to output data for the previous station after tuning a new station.
Set bit 4 (SYNC RST) in the control register during tuning to set the synchronization circuit to the unsynchronized state.
If bit 5 (INT) in the control register is enabled, do not use the post-vertical correction output (data for which bit 7 in the
status flags CNT1 is 1) until frame synchronization is re-established.
Of the DARC FM multiplex processing, this IC performs the processing through error correction (layer 2) without
requiring any special control operations. The IC itself is not able to recognize whether the content of the received data has
changed or whether the system has been tuned to another station. Therefore the application system must use the above
procedure to command the IC not to output the old data and only to output the new data. The synchronization relationship
between the stations is also problematic; although it is rare that the frames of the previous station and the next station
would be synchronized, applications must also perform the processing described above to cancel the frame
synchronization forward protection period.
