... The RXERWT[1:0] register setting defines the time after the PLL is locked until ERRF outputs “L” to cancel the error. The demodulated audio data is output after the ERRF error is canceled, so when problems occur such as the start of the data being cut off, change this setting.

... When the data match, the data is considered to have been updated and the update flag is output. • Likewise, the burst preamble Pc update flag process compares the 16 bits of data of the previous block with the current data. When the data match, the update flag is output. LC89075W-H Address: 0Eh; DIR Interrupt Source Setting D5 ...

... The ERRF, NPCMF and DSTATE pin statuses can be read from the OERROR, OUNPCM and ODATAM registers, regardless of the INTB output setting. • The channel status information can be read from the OEMPF register, regardless of the INTB output setting.

... The RXFSFLG register compares the calculated sampling frequency value of the input data with the fs information of the channel status, and is output when the sampling frequency results match. • When the DTS-CD(ES) sync signal of the RXDTSES register is detected, the DTS-CD sync signal of the RXDTS51 register is also detected at the same time.
