*) Vender ID of AKM is AKM :This ID has been approved by Intel.
*) The AK4543 outputs X bits as 0.
*) A write on Invalid registers will not affect the operation of the AK4543.
*) ANL, DAC, ADC Bit in register 26h are all 0 following cold reset. When each section is ready for normal
operation, the coresponding bit becomes 1. The Powerdown register(26h) is not affected by a write to Reset
register(0h). See Mixer Registers in AC97 specification for details. Vref is controlled only by PR3.

Reset Register (Index 00h)
<Write>
When any value is written to this register, all registers in the AK4543 except for register 26h Powerdown
Ctrl/Stat Register are reset to the default values. The value of this register is not altered.
<Read>
Reading this register returns 2D50hcomposed of the ID code of the part, a code for the type of 3D enhancement,
18
bit ADC/DAC resolution, and a code for True Line Level Out.
*Setting D14 D10 01011 means AKM 3D enhancement which is registered in Audio Codec 97 Component
Specification Rev 1.03 and 2.1 .
*Setting D8 1 indicates 18bit ADC resolution and D61 does DAC resolution.
*Setting D4 1 means True Line Level Out is supported with Volume Control(Index 04h).
n
Play Master Volume Registers (Index 02h,06h) and LINVL(True Line Level Out) Volume Register(Index 04h)
The following table shows the relationship between bits and the attenuation value with step size of 1.5dB. The
AK4543 has a range of 0dB to 46.5dB. The AK4543 does not support the optional MX5 bit.
The AK4543
detect
s
when MX5 is set and set all 5 LSBs to 1s.
Example: When t
he driver
writes a “01xxxxx”
the AK4543
interpret that as “0011111”. When this register is read, the returned value is “0011111”.
