LMK03328: I2C slave address

Hirotaka Matsumoto

Part Number: LMK03328

Hi all

Would you mind if we ask LMK03328?

If you have knowledge, could you share us?

R10 is read register, it depends on GPIO1 only.
With writing reserve resister(or undefined resister), might this value chage?
(Just in case, we confirmed these. We assume there is no this case. )

Kind regards,

Hi Hirotaka,

Bit 0 of this register doesn't do anything so it's OK to overwrite it. The first 5 bits of the I2C address can only be changed through EEPROM and the last 2 bits are controlled by GPIO1.

Thank you so much for your reply!

->We are sorry that we could not find on the data sheet what address corresponds for "The first 5 bits of the I2C address can only be changed through EEPROM".
Is it hidden register or reserve?
Or, is it internal EEPROM?

Kind regards,

Hirotaka Matsumoto
