Function:
Places the S/PDIF receiver and PLL in a reset state. It is advised that any change of these bits be
made while the DACs are muted or the power-down bit (PDN) is enabled to eliminate the possibility
of audible artifacts.
It should be noted that, for Revision C compatibility, PDN_RCVR1 may be set to ‘0’ and receiver op-
eration may be controlled with the PDN_RCVR0 bit.
When enabled the stereo analog to digital converter will remain in a reset state. It is advised that any
change of this bit be made while the DACs are muted or the power-down bit (PDN) is enabled to elim-
inate the possibility of audible artifacts.
When enabled the respective DAC channel pair x (AOUTAx and AOUTBx) will remain in a reset state.
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 can occur.
