REDER

RESEL

RERR output contents setting

0: PLL lock error or data error (initial value)

1: PLL lock error or data error or non-PCM data

REDER

8 continuous times parity error flag output setting

0: Output during non-PCM data recognition. (initial value)

1: Output only during sub-frame for which error was generated.

XTWT [1:0]

Clock switch wait time setting after PLL unlock

00: Clock switching after approx. 200

µs following oscillation amplifier

start

(initial value)

01: Clock switching after approx. 100

µs following oscillation amplifier

start

10: Clock switching after approx. 50

µs following oscillation amplifier

start

11: Clock switching after approx. 400

µs following oscillation amplifier

start

RESTA

RERR output condition setting

0: Output permanent PLL status (Output PLL status even during XIN

source) (initial status)

1: Forcibly output error (Set High forcibly to RERR)

FSERR

Setting of error flag output condition through fs change

0: Reflect fs changes to error flag. (initial value)

1: Do not reflect fs changes to error flag.

ERWT [1:0]

RERR wait time setting after PLL lock

00: Error release preamble B after 48 counts. (initial value)

01: Error release preamble B after 24 counts.

10: Error release preamble B after 12 counts.

11: Error release preamble B after 6 counts.

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.
