7.4.6
MCLK Divide By 2
Divides the input MCLK by 2 prior to all internal circuitry.
Note:
In Slave Mode, this bit is ignored when the AUTO bit (“Auto-Detect” on page 38) is disabled.
7.5
Interface Control 1 (Address 06h)
7.5.1
Master/Slave Mode
Configures the serial port I/O clocking.
7.5.2
SCLK Polarity
Configures the polarity of the SCLK signal.
7.5.3
DSP Mode
Configures a data-packed interface format for the DAC.
Notes:
1.
Select the audio word length using the AWL[1:0] bits (“Audio Word Length” on page 41).
2.
The interface format for the DAC must be set to “Left-Justified” when DSP Mode is enabled.
7.5.4
DAC Interface Format
Configures the digital interface format for data on SDIN.
Note:
Select the audio word length for Right Justified using the AWL[1:0] bits (“Audio Word Length” on
