Multiple codec function
There can be up to 4 Codecs on the extended AC-link. The Primary Codec generates the master AC-link BIT_CLK for
both the AC ’97 Digital Controller and any Secondary Codecs. The AK 4544A may be used as a master or slave in any
systems using more than one codec.
ID for these 4 Codecs is set by combination of ID1# pin and ID0# pin. When AK 4544A operates as primary codec,
ID1# pin and ID0# pin must be open state before power on. In this case ID1 bit and ID0 bit in Extended Audio
register are stored as (0,0) respectively. If either ID1# pin or ID0# pin is connected to DGND or both pins are
connected to DGND, AK 4544A operates as secondary codec.
The slot request bits of ID(0,1) CODEC are same as that of ID(0,0) CODEC. Therefore, note that all sample rates
except 48KHz can’t be used for DAC in the multiple CODEC system which secondary CODEC ID is (0,1).
