12.6 Lock Error and Data Error Signal (ERROR)
ERROR outputs an error flag, when PLL lock error arises or when a data error arises.
The output form of an error signal is chosen by the ERF[1:0] commands.
12.6.1 PLL Lock Error
PLL is unlocked to the data that has lost the pattern of input bi-phase modulation or which preamble B, M and W
cannot be detected.
ERROR outputs high upon occurrence of PLL lock error and outputs low after holding high for 3msec to 300msec
after data demodulation returns to normal. See Figure 12.8.
After PLL is locked, the holding period for high output of ERROR is decided by counting preamble B. Also, this
period is changeable with EWT [1:0] commands.
12.6.2 Input Data Parity Error
Parity bit errors (odd number) of input data and input parity errors are detected.
If nine or more input parity errors occur in succession, ERROR outputs high, and then low after detecting the PLL
lock status and holding high for 3 to 300msecs.
If eight or fewer input parity errors occur in succession, the output format of error flag can be selected with ERF[1:0]
commands.

12.6.3 Others Error
Even when ERROR goes low, channel status bits 24 to 27 (sampling frequency) are continuously sampled and the
previous block of data and the current data are compared. If they are different, ERROR goes high immediately and the
same processing as for the PLL lock error is performed. However, even if input data changes after ERROR goes low
and the channel status information does not change, or if the input data changes within the PLL capture range,
ERROR does not go high.
