Mode Control 2 (Address 02h)
Power Down (PDN)
Default = 1
0 - Disabled
1 - Enabled
Function:
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.
Digital Interface Format (DIF)
Default = 000 - Format 0 (Left Justified, up to 24-bit data)
Function:
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
Note:
to ensure proper switching from one mode to another.
