Description of level meter mode (see the Timing Chart 1-4.)
• When this LSI is set to this mode, it can possess digital level meter functions.
• When the 96-bit clock is input to SQCK, 96 bits of data are output to SQSO.
The initial 80 bits of data are Sub Q data (see §2. Subcode Interface). The last 16 bits are LSB first 15-bit
PCM data (absolute values). The final bit is PCM data. However, it is high when generated by the left
channel and low when generated by the right channel.
• PCM data is reset and the L/R flag is reversed after one readout.
The maximum value for this status is then measured until the next readout.
