DAC Digital Interface Format (DAC_DIF[2:0])
Default = 000
Function:
Selects the digital interface format used for the data in on SDIN. The required relationship between the
Left/Right clock, serial clock and serial data is defined by the Digital Interface Format and the options are
detailed in the section
ADC I²S or Left-Justified (ADC_I²S/LJ)
Default: 0
0 - Left-Justified
1 - I²S
Function:
Selects either the I²S or Left-Justified digital interface format for the data on SDOUT. The required relation-
ship between the Left/Right clock, serial clock and serial data is defined by the Digital Interface Format and
the options are detailed in the section
Digital Mix (DIGMIX)
Default: 0
Function:
Selects between the ADC or a digital mix of the ADC and DAC into the serial port to the SDOUT pin. This
mix function is affected by the data select bits DATA_SEL[1:0].
Microphone Mix (MICMIX)
Default: 0
0 - Disabled; No Mix: Left/Right Channel to ADC serial port, SDOUT.
1 - Enabled; Mix: Differential mix ((A-B)/2)to ADC serial port, SDOUT.
Function:
Selects between the ADC stereo mix or a differential mix of analog inputs A and B.
