9.4.5 Data processing upon occurrence of errors (lock error, parity error)
The data processing upon occurrence of an error is described below. If 8 or fewer input parity errors occur in
succession and transfer data is PCM audio data, the data is replaced by the one saved each in L-ch and R-ch in the
previous frame. However, if the transfer data is non-PCM data, the error data is output as is. Non-PCM data is the
data of when bit 1 non-PCM data detection bit of the channel status turns to "H" based on the data detected prior to
the occurrence of the input parity error.
Output data is muted when a PLL lock error occurs or a parity error occurs 9 or more times in succession.
As for the channel status output, the data of the previous block is held in 1bit units when a parity error occur 8 or
fewer times in succession.

* Input parity error (a): If occurs 9 or more times in succession
* Input parity error (b): If occurs 8 or fewer times in succession, in case of audio data
* Input parity error (c): If occurs 8 or fewer times in succession, in case of non-PCM burst data
Figure 9.11 shows an example of data processing upon occurrence of a parity error.
