CS4365

6.2.3

PCM/DSD Selection (DSD/PCM)

Default = 0

0 - PCM

1 - DSD

Function:

This function selects DSD or PCM Mode. The appropriate data and clocks should be present before

changing modes, or else MUTE should be selected.

6.2.4

DAC Pair Disable (DACx_DIS)

Default = 0

0 - Enabled

1 - Disabled

Function:

When enabled, the respective DAC channel pairx (AOUTAx and AOUTBx) will remain in a reset state. It

is advised that changes to these bits be made while the power-down bit is enabled to eliminate the pos-

sibility of audible artifacts.

6.2.5

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.

6.3

PCM Control (address 03h)

6.3.1

Digital Interface Format (DIF)

Default = 0000 - Format 0 (Left-Justified, up to 24-bit data)

Function:

These bits select the interface format for the serial audio input. The DSD/PCM bit determines whether

PCM or DSD Mode is selected.

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 8 through through 17.
