Bit Name

Description

RxMUTE

Hard-mutes the audio output for the AES3/S/PDIF receiver.

0 = AES3/S/PDIF receiver is not muted.

1 = AES3/S/PDIF receiver is muted.

SP_PLL

AES3/S/PDIF receiver PLL accepts a left/right clock from one of the four serial ports as the PLL reference clock.

0 = Left/right clock generated from the AES3/S/PDIF preambles is the reference clock to the PLL.

1 = Left/right clock from one of the serial ports is the reference clock to the PLL.

SP_PLL_SEL[1:0]

Selects one of the four serial ports as the reference clock to the PLL when SP_PLL is set.

00 = Playback port is selected.

01 = Auxiliary input port is selected.

10 = Record port is selected.

11 = Auxiliary output port is selected.

NO NONAUDIO

When the NO NONAUDIO bit is set, data from the AES3/S/PDIF receiver is not allowed into the sample rate converter

(SRC). If the NO NONAUDIO data is due to DTS, AAC, and so on, as defined by the IEC61937 standard, then the data

from the AES3/S/PDIF receiver is not allowed into the SRC regardless of the state of this bit.

0 = AES3/S/PDIF receiver data is sent to the SRC.

1 = Data from the AES3/S/PDIF receiver is not allowed into the SRC, if the NO NONAUDIO bit is set.

NO_VALIDITY

When the NO_VALIDITY bit is set, data from the AES3/S/PDIF receiver is not allowed into the SRC.

0 = AES3/S/PDIF receiver data is sent to the SRC.

1 = Data from the AES3/S/PDIF receiver is not allowed into the SRC, if the NO_VALIDITY bit is set.
