Operation sequence 1) Set up the power supply lines (Please refer the wiring of " set up other jumper ") Terminal Name Color Vp Red +12V GND Orange Black Supply Voltage 48V 12V 0V Items Note
VP1, 2, 3 pins of AK4730 Should be connected MVDD pin of AK4730, the Should be connected regulator and so on. All GND of AK4730 Should be connected Table 1. Wiring of the power supply
Please wire the power supply carefully. (Divide wiring from each power supply) 2) Setup of each clocks to AK4730 The input method of the clocks to AK4730 has two kinds of methods. One method is from the mounted AK4114, another is from the external inputs. These setting is selected by the jumpers of JP1(MCLK), JP2(BICK), JP3(LRCK), JP4(SDATA). (see the following Figures)

AKD4730-100W Control Program operation manual
Set-up of evaluation board and control software
This evaluation board does not correspond to I C control.
Operation flow
Keep the following flow. 1. Start a control program in accordance with the above. 2. Next, it should input and output data properly, and evaluate it.
Explanation of each buttons
1. Write default : 2. All write : 3. All Read : 4. F1 : 5. F2 : 6. Volume : 7. Read : 8. Write : initialize the registers of AK4730 The setting data of all registers on PC display is written to the AK4730 at the same time. The setting data of all registers of the AK4730 is read out at same time. Dialog to write data by keyboard operation. Dialog to evaluate ATTL / ATTR Volume and Tone can be changed by the slider buttons The setting data of each register is read The setting data of each register is written. "ON" / "OFF" at each bit are set up by click.
If you want to write the input data to AK4730, click "OK" button. If not, click "Cancel" button.
The indication of the data
The inputted data is indicated at the register map. Red character means "H" and "1", Blue character means "L" and "0". The blank part is the part which is not defined by the datasheet.

Explanation of each dialog
1. Function1 Dialog : Address Box: Data Box: Dialog to write data by keyboard operation
Input register address in 2 figures of hexadecimal. Input register data in 2 figures of hexadecimal.
If you want to write the input data to AK4730, click "OK" button. If not, click "Cancel" button.
2. Function2 Dialog :
Dialog to evaluate ATTL / ATTR
4. Write Dialog : Dialog to write data by the mouse operation There are dialogs corresponding to each register. Click the "Write" button corresponding to each register to set up the dialog. If you check the check box, data becomes "H" or "1". If not, "L" or "0". If you want to write the input data to AK4730, click "OK" button. If not, click "Cancel" button.

Attention on the operation
In the case that the function of "Output-Short Protection" is used Write "1" to PW bit after PROT bit was written "1". In the case that the function of "Adaptive Dead-Time Control" is used Write "1" to ADTC bit after PW bit was written "1". If you set up Function1 or Function2 dialog, input data to all boxes. Attention dialog is indicated if you input data or address that is not specified in the datasheet or you click "OK" button before you input data. In that case set up the dialog and input data once more again. These operations does not need if you click "Cancel" button or check the check box.
