8.5 Error Output Processing (ERROR)
8.5.1 Lock error and data error output
8.5.2 PLL lock error
8.5.3 Input data transmission error
8.5.4 Other errors
The ERROR pin outputs high level when a PLL lock error happens or an error occurs in the transmitted data.
The PLL circuit will unlock the input data which does not conform to the bi-phase modulation rules or can not detect
ERROR turns to H when a PLL lock error occurs. When data modulation returns to the normal state, it remains high
The output of ERROR is synchronized with LRCK.
An odd number of input parity errors are detected from the parity bits in the input data.
When input parity errors occur 9 times or more in a row, ERROR turns to high level. After the high level is held for
When 8 or fewer input parity errors occur consecutively, an error is output only for intervals between sub-frames
Even when ERROR has turned to low, the LC89052T always acquires bits 24 to 27 (sampling frequency) of the

15m to 50ms following the detection of the PLL lock state, the ERROR returns to low level.

and the processing similar to that for the PLL lock error is carried out.
