Hello Team,

Add 3rd question:

3. What does Table 156 AEQ_STATUS b[5:0] mean?
Does the AEQ_Status show overall EQ dB value?

Thank you.
Regards,
Ting

Hi Ting,

1. EQ is composed of two stages with 6bits b[5:0], one is EQ stage1, the other is EQ stage2, which are included in register 0xd4. You can refer to below table.

2. regarding the gain step, it is roughly ~1.8dB. For -21dB insertion loss, the AEQ selection is about between 11 and 12 for your reference.

best regards,

Steven
