Function:
Divides the input MCLK by 2 prior to all internal circuitry. This bit is ignored when the AUTO bit is disabled
in Slave Mode.
Interface Control (Address 04h)
Master/Slave Mode (M/S)
Default: 0
0 - Slave
1 - Master
Function:
Selects either master or slave operation for the serial port.
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
