The next figure illustrates a state when all the mixers should work with the static volume settings that are
contained in their associated registers. This is used when the user is playing a CD (or external LINE_IN source)
through the AC 97 codec to the speakers but has most of the system in a low power mode. The procedure for this
follows the previous except that the analog mixer is never shut down.

AK4543 Powerdown/Powerup flow with analog still alive
n
Powerdown/Powerup sequence of multiple codec configuration
There can be up to 4 Codecs on the extended AC-link. Multiple Codec AC-link implementations must run off a
common BIT_CLK. The Primary Codec generates the master AC-link BIT_CLK for both the AC 97 Digital
Controller and any Secondary Codecs. The AK4543 may be used as a master or slave in any systems using more
than one codec.

Multiple Codec Example
Under the multiple codec circumstances, there is no restriction on setting PR0(ADC), PR1(DAC),
PR2(Mixer), PR6(LNLVL_OUT) and PR7(EAPD) to 1 or 0.
As suggested in the AC97 Specification Rev2.1, the AC-Link Powerdown(PR4) and Vref
Powerdown(PR5=1) under the Multiple codec configuration are NOT recommended in order to continue
supplying BIT_CLK to the Secondary codecs.
