4-9. CD-TEXT Data Demodulation
In order to demodulate the CD-TEXT data, set Data 6 D3 TXON command of $8 to 1.
During TXON = 1, the EXCK pin should be set to low and the SBSO output data should not be used because
the CD-TEXT demodulation circuit uses EXCK and SBSO exclusively.
It requires 26.7ms (max.) to demodulate the CD-TEXT data properly after TXON is set to 1.
The CD-TEXT data is output after the SQSO pin is switched by the command. The CD-TEXT data can be
output by setting Data 6 D2 TXOUT command of $8 to 1. The readout clock should be input to SQCK in
order to read the data.
The data which can be read out is the CRC calculation results for each pack (CRC), CD-TEXT data
excluding CRC data (16 bytes).
When the CD-TEXT data is read, the order of the MSB and LSB is inverted within each byte. As a result,
although the sequence of bytes is the same, the bits within the bytes are now ordered LSB first.
The data which can be stored in the IC is for 1 packet (4 packs).
