When this bit is set to “0”, some digital blocks of the AK4129 are powered-down. In this case SRC1-3

can not operate. Control register settings are not initialized because I²C serial control interface and
control register blocks are not powered-down. Control register writings are available. The internal
oscillator for the clocks, the regulator and the reference voltage generation circuit are not powered-down.
In serial control mode (SPB pin= “H”), the SMUTE pin setting is ignored. SRC1 reflects the SMUTE1
bit setting.
In serial control mode (SPB pin= “H”), the SMUTE pin setting is ignored. SRC2 reflects the SMUTE2
bit setting.
In serial control mode (SPB pin= “H”), the SMUTE pin setting is ignored. SRC3 reflects the SMUTE3
bit setting.
