TAS5768M register of Volume and gain and conversion volume to hex

Hi,

TAS5768M datasheet describes about volume as below.

＞Volume block, from -110 db to +6 dB with 0.5 dB steps, including a fixed gain block of 0dB to 12 dB gain

It means volume register has 232 step and gain block register has 13 step.

1)Where is Volume and gain register?

Dumping my EVM of volume setting in case of -11.5dB and 0dB, There is difference between Arddress:0x08-0x0A of Page44(0x2C).

Volume setting = -11.5dB:

// Coefficient Memory A

// page 44 (0x2C)

    { 0x00, 0x2C },

    { 0x08, 0x11 },

    { 0x09, 0x07 },

    { 0x0A, 0x54 },

Volume setting = 0dB:

// Coefficient Memory A

// page 44 (0x2C)

    { 0x00, 0x2C },

    { 0x08, 0x40 },

    { 0x09, 0x00 },

    { 0x0A, 0x00 },

2)How can I conversion hex to volume and gain?

Anyone has conversion or Equivalent?

 2727.Vol Calc dB-Hex.xlsx

My attached file is calcuration to convert Volume to dB-HEX.

Is it correct calc?

Best regards,
