12.7.2 Upon Error Recovery (Lock)
When preamble B, M and W are detected, PLL is locked and data demodulation begins.
DATAO and DATAO2 output data are output from the L/R clock edge after ERROR goes low.
The start timing of the ERROR flag, and the DATAO and DATAO2 output data are shown in Figure 12.8.
The above operation is in case the delay setup is not done. For information on operations with delay settings, see
section “13. Output Data Delay Function”.
Figure 12.8 Data Processing at Data Demodulation Start (non delay setting)
12.8 Channel Status Emphasis Information Output (EMPHA)
EMPHA outputs channel status information that indicates the presence or absence of 50/15sec pre-emphasis.
EMPHA is output immediately after the detection of ERROR even during high output.

12.9 Channel Status Bit 1 Output (AUDIO)
AUDIO outputs bit 1 of the channel status that indicates whether transfer data has PCM audio data or data other than
audio.
AUDIO is output immediately after the detection of ERROR even during high output.
