Default = 000 - Format 0 (Left Justified, up to 24-bit data)
These bits select the interface format for the serial audio input. The Functional Mode bits determine
whether PCM or DSD mode is selected.
PCM 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 Figures 33-38.
DSD Mode: The relationship between the oversampling ratio of the DSD audio data and the required
Master clock to DSD data rate is defined by the Digital Interface Format pins.
The entire device will enter a low-power state when this function is enabled, and the contents of the
control registers are retained in this mode. The power-down bit defaults to ‘enabled’ on power-up and
must be disabled before normal operation in Control Port mode can occur.
