5.2.2 FREEZE CONTROLS (FREEZE)

Default = 0

0 - Disabled

1 - Enabled

Function:

This function allows modifications to be made to the registers without the changes taking effect until

the FREEZE is disabled. To make multiple changes in the Control port registers take effect simulta-

neously, enable the FREEZE Bit, make all register changes, then Disable the FREEZE bit.

5.2.3 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.

5.2.4 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

possibility of audible artifacts.

5.2.5 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.
