Description
MUTE_SRC
Soft-mutes the output of the sample rate converter.
0 = No mute.
1 = Soft mute.
GRPDLY[6:0]
Adds delay to the sample rate converter FIR filter by GRPDLY[6:0] input samples.
0000000 = No delay.
0000001 = 1 sample delay.
0000010 = 2 sample delay.
1111110 = 126 sample delay.
1111111 = 127 sample delay.

Description
NOCLOCK
Selects the source of the receiver clock when the PLL is not locked.
0 = Recovered PLL clock is used.
1 = ICLK1 is used.
RxCLK[1:0]
Determines the oversampling ratio of the recovered receiver clock.
00 = RxCLK is a 128 × fS recovered clock.
01 = RxCLK is a 256 × fS recovered clock.
10 = RxCLK is a 512 × fS recovered clock.
11 = Reserved.
AUTO_DEEMPH
Automatically de-emphasizes the data from the receiver based on the channel status information.
0 = Automatic de-emphasis is disabled.
1 = Automatic de-emphasis is enabled.
ERR[1:0]
Defines what action the receiver should take, if the receiver detects a parity or biphase error.
00 = No action is taken.
01 = Last valid sample is held.
10 = Invalid sample is replaced with zeros.
11 = Reserved.
LOCK[1:0]
Defines what action the receiver should take, if the PLL loses lock.
00 = No action is taken.
01 = Last valid sample is held.
10 = Zeros are sent out after the last valid sample.
11 = Soft-mute of the last valid audio sample.
