12.7 Output Data Error Processing
12.7.1 Upon Error Occurrence (Lock Error and Parity Error)
The data processing upon error occurrence is described below. If input parity errors occur eight times or more in
succession, transfer data is replaced by the data held in L-ch and R-ch of the previous frame in the case of PCM audio
data. However, if the data is Non-PCM burst data, error data is output without change as the transfer data. Non-PCM
burst data is detected based on data detected prior to occurrence of an input parity error when channel status bit 1 goes
high or when burst preamble Pa and Pb are detected.
For the channel status, the data of the previous block is held in bit when a parity error occurs, regardless of the data type.
Output data is muted upon occurrence of a PLL lock error or nine continuous parity errors.
