Read/Write Mode Control
When W/R = 0, a Write operation is performed.
When W/R = 1, a Read operation is performed.
Default Value: 0
Output Phase Reversal
This bit is Read/Write.
Default Value: 0
The REV bit is used to invert the output phase for both the Left and Right channels.
Attenuation Rate Select
This bit is Read/Write.
Default Value: 00
The ATS[1:0] bits are used to select the rate at which the attenuator is decremented or incremented during level
transitions.
DAC Operation Control
This bit is Read/Write.
Default Value: 0
The OPE bit is used to enable or disable the analog output for both channels. Disabling the analog outputs forces
them to the bipolar zero level (BPZ), ignoring the audio data input(s).
SCKO Frequency Selection
This bit is Read/Write.
Default Value: 0
The CLKD bit is used to determine the output frequency at the system clock output pin, SCKO.
SCKO Frequency Enable
This bit is Read/Write.
Default Value: 0
The CLKE bit is used to enable or disable the system clock output pin, SCKO.
