6.5.1 DIGITAL INTERFACE FORMAT (DIFX)
Default = 01
Function:
These bits select the digital interface format used for the CODEC Serial Port and Serial Audio Interface
Port when not in One-Line Mode. 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 11-12.
6.5.2 ADC ONE_LINE MODE (ADC_OLX)
Default = 00
Function:
These bits select which mode the ADC will use. By default, One-Line Mode is disabled, but it can be
selected using these bits. Please see Figures 13 and 14 to see the format of One-Line Mode 1 and
One-Line Mode 2.
6.5.3 DAC ONE_LINE MODE (DAC_OLX)
Default = 00
Function:
