96 kHz IEC 958 audio DAC UDA1351H
8.7.9.5 PCM detection
A 1-bit value which indicates whether the IEC 958 input
contains PCM audio data or other binary data.
Table 27 Two-channel PCM input detection
8.7.9.6 Pre-emphasis detection
A 1-bit value which indicates whether the pre-emphasis bit
was set on the IEC 958 input signal or not set.
Table 28 Pre-emphasis detection
8.7.9.7 Clock accuracy detection
A 2-bit value indicating the timing accuracy of the IEC 958
input signal is conforming to the IEC 958 specification.
