Figure 5. SW201 Power-up/down switch direction
Power-down reset by SW201 (PDN) must be made once after power up the evaluation board. Put the SW201 to “L”
for power-down reset of the AK4490EN, AK8157A and AK4118A, and the return it to “H” to release the
power-down states.
[SW201] (PDN): Resets the AK4490EN, AK8157A and AK4118A (Keep “H” during normal operation).
This switch must be set to “L” once upon power up the evaluation board to reset the AK4490EN,
AK8157A and AK4118A.
*Caution
When changing from power on (power off) to power off (power on), please remove the headphone from ear. Ear

Operation Overview
Function and Register map are controlled by this control software. These controls may be selected by the upper tabs.
Frequently used buttons, such as the register initializing button “Write Default”, are located outside of the switching
tab window.
1.[Port Reset]: Resets the connection to PC.
Click this button when connecting USB cable after the control software set up.
2.[Write Default]: Register Initialization.
When the device is reset by a hardware reset, use this button to initialize the registers.
3.[All Write]: Executes write commands for all registers displayed.
4.[All Read]: Executes read commands for all registers displayed.
5.[Save]: “Save Address of Register” dialog box pops up.
6.[Load]: Executes data write from a saved file.
7.[All Reg Write]: “All Reg Write” dialog box pops up.
8.[Sequence]: “Sequence” dialog box pops up.
9.[Sequence (File)]: “Sequence (File)” dialog box pops up.
10. [Read]: Reads current register settings and displays to the register area (on the right of the main window).
(Add: Address, R: Read value, W: Last Write value (= Register Map))
This is different from [All Read] button as it does not reflect to the register map. It only displays register
values in hexadecimal numbers.
