Address 0x0126 SRC Delay Register (Default: 0x0000)
This register is used to set the delay for the SRC channel.

Description
Default
Bits[15:12]
Reserved
Always write as 0 if writing to this register.

Bits[11:0]
SRC delay
The range of values is 20.83 μs to 42 ms in 20.83 μs (1 sample delay) steps.
000000000000
0x000 = 20.83 μs (1 sample delay)
0x001 = 41.66 μs (2 sample delay)
...
0x7E1 = 42 ms (2017 sample delay)
Address 0x0127 SRC Control Register (Default: 0x0030)
This register is used to enable the DSP mute circuit for SRC1 and SRC2. If SRC is enabled and detects an error, it will mute the output of
the SRC. It also bypasses the de-emphasis filters of the SRC.

Description
Default
Bits[15:6]
Reserved
Always write as 0 if writing to this register.
0000000000
Bit[5]
SRC1 de-emphasis filter bypass
This bypasses the SRC1 de-emphasis filter.
0
0b = bypass
1b = enabled
Bit[4]
SRC2 de-emphasis filter bypass
This bypasses the SRC2 de-emphasis filter.
0
0b = bypass
1b = enabled
Bit[3]
SRC1 DSP mute circuit bypass
If an error is detected, it mutes the output of SRC1.
0
0b = enabled
1b = disabled
Bit[2]
SRC2 Channel A DSP mute circuit bypass
If an error is detected, it mutes the output of SRC2.
0
0b = enabled
1b = disabled
Bit[1]
SRC2 Channel B DSP mute circuit bypass
If an error is detected, it mutes the output of SRC2.
0
0b = enabled
1b = disabled
Bit[0]
SRC2 Channel C DSP mute circuit bypass
If an error is detected, it mutes the output of SRC2.
0
0b = enabled
1b = disabled
