SFSY is subcode frame synchronization signal. P, Q, R, S, T, U, V, and W subcodes are read out by sending clock
eight times to SBCK.
WRQ goes high when Q subcode data passes the CRC check. Through external connection and sending of CQCK,
data is read from SQOUT. Set MSB-first/LSB-first to low when data in LSB-first format is desired.
Command is generated by sending output synchronized with CQCK command data after setting microprocessor RWC
to high.
