Control Program Compatibility
This IC allows the majority of the control software used to be compatible with Sanyo’s other FM multiplex ICs, in
particular, the LC72700E, LC72705E, LC72706E, LC72708E, and LC72709E(W). However, the following aspects of
the control software require modification.
Values of the register addresses
The addresses of the allowable BIC error count, synchronization error protection count, control registers, the layer 4
CRC register, and other registers have been modified.
The CCB address for serial I/O over a CCB bus has not been changed.
INT signal output timing
The INT signal output timing for data output is as follows. A circle ("O") indicates that INT is output, and a cross ("X")
indicates that the signal is not output.
Notes on Output Data Selection after Tuning (Reference)
When building an FM multiplex reception system, a tuning system is an absolute necessity. However, if it is
unacceptable for the IC to output data from the old station after tuning to a new station, the application must perform the
following processing.
(1) At the same time as tuning a new station, the application must set bit 4 (SYNC_RST) in control register 1 to set the
synchronization circuit to the unsynchronized state.
(2) Under the default settings, after the synchronization reset applications must acquire data according to the issued INT
signal.
The post-vertical correction output is not provided by the IC until frame synchronization has been established for the
new station after tuning and the first vertical correction operation has been performed.
(3) If bit 2 (VEC_OUT) in control register 2 has been enabled, applications must not use the post-vertical correction
output (data for which bit 7 in the status register is high) until frame synchronization has been reestablished.
This IC performs the portion of the DARC FM multiplex processing through layer 2 error correction without requiring
any special control operations. The IC itself cannot determine if the contents of the received data have changed or if a
new station has been tuned. This means that applications must use the procedure described above for this IC not to output
old data and only output the new data. Another point is that in IC synchronization, although it is rare for the old station
and the new station to be frame synchronized, applications need to perform the processing in item 1 above to cancel
frame synchronization forward protection period.
Notes:1. Data for which horizontal correction failed, but for which vertical correction succeeded is output.
2. All data is output.
3. If there is data for which horizontal correction failed, the post-vertical correction data for that data is output, regardless of whether or not vertical
correction succeeded.
(If the IC performs vertical correction, post-vertical correction data will be output.)
