„ Evaluation mode
In case of the AK4691 evaluation using the AK4114, it is necessary to correspond to audio interface format
for the AK4691 and AK4114. About the AK4691’s audio interface format, refer to datasheet of the AK4691.
About the AK4114’s audio interface format, refer to Table 2.
The AK4114 operates at fs of 32kHz or more. If the fs is slower than 32kHz, please use other mode.
In addition, MCLK of AK4114 supports 256fs and 512fs. When evaluate it in a condition except this, please
use other mode.
About the setup of the AK4691’s register, refer to datasheet of the AK4691.
