Interface Formats (Address 04h)
Freeze Controls (FREEZE)
Default = 0
Function:
This function will freeze the previous settings of, and allow modifications to be made to the channel mutes,
the DAC and ADC Volume Control/Channel Invert registers without the changes taking effect until the
FREEZE is disabled. To have multiple changes in these control port registers take effect simultaneously,
enable the FREEZE bit, make all register changes, then disable the FREEZE bit.
Auxiliary Digital Interface Format (AUX_DIF)
Default = 0
0 - Left Justified
1 - I²S
Function:
This bit selects the digital interface format used for the AUX Serial Port. 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
DAC Digital Interface Format (DAC_DIF[2:0])
Default = 110
Function:
These bits select the digital interface format used for the DAC Serial Port. The required relationship between
the Left/Right clock, serial clock and serial data is defined by the Digital Interface Format; the options are
detailed in the section
