§4-10. CD TEXT Data Demodulation
• In order to demodulate the CD TEXT data, set the command $8 Data 6 D3 TXON to 1. During TXON = 1,
connect EXCK to low and do not use the data output from SBSO because the CD TEXT demodulation circuit
uses EXCK and the SBSO pin exclusively.
It requires 26.7ms (max.) to demodulate the CD TEXT data correctly after TXON is set to 1.
• The CD TEXT data is output by switching the SQSO pin with the command. The CD TEXT data output is
enabled by setting the command $8 Data 6 D2 TXOUT to 1. To read data, the readout clock should be input
to SQCK.
• The readable data are the CRC counting results for the each pack and the CD TEXT data (16 bytes) except
for CRC data.
• 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 the bytes is the same, the bits within the bytes are now ordered LSB first.
• Data which can be stored in the LSI is 1 packet (4 packs).
