BCOS0
Selects an internally generated bit clock for audio serial data output to
the SDO0 terminal.

the change point of
LRCK
0
SOFMT0 Selects whether audio serial data output to the SDO0 terminal are to
be effective data after the change point of LRCK or 8 clock shifted.
1
8 clock shifted
Note 3: Normally set only once at initialization.
Data can be set in CNT-R2 asynchronously with the SYNC signal.
Note 4: When a channel clock or bit clock is externally input, (LROS bits 2~0 set to “1”), the data can be
output to pins SDO2~0 with 8 clock shifted by setting SOFMT~0.
Data can also be output with 8 clock shifted by program (operation) without the above setting.
