The frequency of IMCLK1, IMCLK2, and OMCLK are fixed based on the sampling rate and clock speed (256fs/512fs).
IMCKS1, IMCKS2 and OMCKS bits in register 01H select clock speed.
n Volume
AK4120 has two digital volumes (Volume#1 and Volume#2). Volume#1 can control the volume level of data from
Input#1 while in Path Mode 0 or from Input#2 while in Path Mode 1. It then passes this data through SRC block.
Volume#2 can control the volume level of data from Input#2 while in Path Mode 0 and Path Mode 3, or from Input#1
in Path Mode 2. These volume ranges are from –83.25dB to 12dB in 0.75dB steps. The volume level and mute of each
channel can be controlled by register 3-6H.
