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.
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
One-Line Mode 2.
These bits select which mode the DAC will use. By default, One-Line Mode is disabled, but it can be
