RERR output setting:
Non-PCM data is reflected as data defined by AOSEL and matches the AUDIO pin output.
Output data is muted if an error occurs due to non-PCM data RESEL.
The RESTA setting is not reflected to the data and clock output pins.
When FSERR is set the fs calculation result (when the oscillation amplifier is stopped) is not
reflected. In this case, fs changes reflect only of channel status fs information.
ERWT[0:1] defines the interval after which an RERR error is cancelled (Low) following a PLL lock. Do
not perform this setting if cutting off of the beginning of data is a problem.
