5.2.2
CS4384
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 simultaneously,
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 pos-
sibility 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.
