Interface Control 1 (Address 06h)
MCLK Divide By 2
Divides the input MCLK by 2 prior to all internal circuitry.
Note:
Master/Slave Mode
Configures the serial port I/O clocking.
SCLK Polarity
Configures the polarity of the SCLK signal.
DSP Mode
Configures a data-packed interface format for the DAC.
Notes:
1. Select the audio word length using the AWL[1:0] bits
2. The interface format for the DAC must be set to “Left-Justified” when DSP Mode is enabled.
DAC Interface Format
Configures the digital interface format for data on SDIN.
