AUDIO SERIAL PORT MODE
Both Serial Ports are in Slave Mode (default)
Output Serial Port is Master with RCKI = 128fs
Output Serial Port is Master with RCKI = 512fs
Output Serial Port is Master with RCKI = 256fs
Both Serial Ports are in Slave Mode
Input Serial Port is Master with RCKI = 128fs
Input Serial Port is Master with RCKI = 512fs
Input Serial Port is Master with RCKI = 256fs
BYPASS
Bypass Mode
This bit is logically OR’d with the bypass input (BYPA or BYPB) for the corresponding SRC section.
BYPASS
0
1
FUNCTION
Bypass Mode disabled with normal ASRC operation. (default)
Bypass Mode enabled with data routed directly from the input port to the output port, bypass-
ing the ARSC function.
MUTE
Output Soft Mute
This bit is logically OR’d with the MUTE input (MUTEA or MUTEB) for the corresponding SRC section.
MUTE
0
1
OUTPUT MUTE FUNCTION
Soft mute disabled. (default)
Soft mute enabled with output data attenuated to all 0s
TRACK
Digital Attenuation Tracking
TRACK
0
ATTENUATION TRACKING
Tracking Off: Attenuation for the Left and Right channels is controlled independently by Con-
trol Register 4 and Control Register 5. (default)
Tracking On: Left channel attenuation setting is used for both channels.
1
PDN
Power-Down
Setting this bit to 0 will force the corresponding SRC section into Soft Power-Down mode. All other register
settings are preserved and the SPI port remains active. Setting this bit to 1 will power-up the corresponding
SRC section using the current register settings.
This bit defaults to 0 on power-up or reset. It must be programmed to 1 by the user in order to enable normal
operation for the corresponding SRC section.
