*) Vender ID of AKM is “AKM” :This ID has been approved by Intel.
*) The AK4545 outputs “X” bits as “0”.
*) A write on “Invalid” registers will not affect operation of the AK4545 .
*) 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 AC’97 specification for details. Vref is controlled only by PR3.
nReset Register (Index 00h)
<Write>
When any value is written to the AK4545 , all registers including 2Ah, 2Ch, and 32h in the AK4545 except for 26h
Powerdown/Control Register are reset to default values. The value of this register is not altered.
<Read>
Reading this register returns “2D50h”composed 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” means 18bit ADC resolution and D6 ”1” means 18bit DAC resolution.
*Setting D4 “1” means True Line Level Out is supported with Volume Control(Index 04h).
