Default value: 0 (valid)
The VALIDL bit controls the validity bit for L-channel in compliance with IEC958.
Default value: 0 (valid)
The VALIDR bit controls validity bit for R-channel in compliance with IEC958.
Default value: 0
SPDIF = 0
DOUTS disabled (default)
SPDIF = 1
DOUTS enabled
The SPDIF bit controls output from DOUTS pin. In case of default, DOUTS always becomes LOW status.
Default value: 0001 (24 bits)
The WL[35:32] bits control bits[35:32] of channel status bits and the actual data word length of audio sample
word including auxiliary 4-bits from DOUTS pin in compliance with IEC958. If the WL[35:32] bits indicate 16 bits,
the actual data word length of audio sample word is limited to 16 bits even though data input on DIN pin is
24-bits, for example.
