TAS5805M: Question of TAS5805 Volume Control Function with Book 0x8C Page 0x2A Register 0x2A

Part Number: TAS5805M
Other Parts Discussed in Thread: TAS5805

Hi Sirs,

The TAS5805 Linux driver implements volume control with Book 0x8C, Page 0x2A, Register 0x24, while it is not specified in the TAS5805 datasheet.
Would you pls advise the function of the register 0x24 and the difference with  the DIG_VOL_CTRL on Book 0x00, Page 0x00, Register 0x4C?
