12.5 Serial Audio Data Input and Output
12.5.1 Output Data Format (DATAO, DATAO2, DOSEL0, DOSEL1)
DATAO and DATO2 output the digital data after demodulation. DATAO2 should be switched by the VSEL
command since DATAO2 is sharing pin with validity flag output.
The output data format is set with DOSEL0 and DOSEL1 terminals, or the DOSW command. The output data is 24bit
I2S output when setup is DOSW=1. The setup of DOSW is given priority over DOSEL0 and DOSEL1.

Data is output in synchronization with the falling edge of BCK from the edge of LRCK immediately after the ERROR
flag goes low. However, this is the case that the delay setup is disabled (initial setting). When the delay setup is
effective, DATAO is output after the delay time set. The delay setting is not applicable to DATA02. For information
about these settings, see section “13. Output Data Delay Function”.
