8.5.5 Data processing upon occurrence of errors
This section describes the data processing performed when an error occurs. When up to 8 consecutive input parity
errors occur, if the transmitted data is PCM audio data, the data is replaced with the corresponding left and right
channel data from the immediately preceding frame. However, if the transmitted data is non-PCM data, the error data
is output as it is. Non-PCM data is based on the data that is detected before the input parity error has occurred, and is
the data for which the channel status bit 1 non-PCM data detection bit is "1". Non-PCM data refers to the data
established when bit 1 non-PCM data detection bit of the channel status turns to high based on the data detected prior
to the occurrence of the input parity error.
The output data when a PLL lock error or 9 or more parity errors occur consecutively are muted.
For the channel status data, the data for the previous block held in 1 bit units is output when an 8 or less parity error
occurs successively.

1) Input parity error (a):
When 9 or more consecutive parity errors occur
2) Input parity error (b):
When up to 8 consecutive parity errors occur in audio data
3) Input parity error (c):
When up to 8 consecutive parity errors occur in non-PCM burst data
The figure below presents an example of the data processing performed when a parity error occurs.
