LMK03328: How to change slave addresses in TICS Pro

Masashi Wada

Prodigy 10 points

Part Number: LMK03328

Hi.

I am using the LMK03328 to generate the clock.
While writing to the LMK03328 via I2C using TICS Pro, data cannot be written.
I did a search for the I2C slave address and the address I found was 0x7F, and when I read register R10, it changed from 0x57 to 0x7F.

The datasheet shows how to rewrite byte11 in the EEPROM, but I don't know how to rewrite byte11 in TICS Pro.
Also, R10 is read-only, so changing it did not return it.
I am operating in SW Mode because HW_SW_CTRL=0.

Please tell me how to do it.

best regards,
Masa

Hi Masa,

in order to communicate with the device, please follow these steps:

1. Click on Interface:

2. click on "Scan I2C Bus"

3. You should see a window that the device was found on address 0x?? -> Click ok.

4. Close "Communication Setup" window.

Now you should be able read/write to the device.

regards,

Julian

Hi Julian,

Thank you for your response.

But instead of this answer.

The slave address has changed and all [7 : 3] in Byte 11 are High.

I would like to know how to rewrite the contents of Byte 11 of the EEPROM.

best regards,
Masa

Hi Masa,

the EEPROM write sequence is described in the datasheet section "10.5.5 Write EEPROM".
