Part Number: CDCE913
Although some time has passed, I would like to report that the issue discussed in the thread below has been resolved.
The root cause was on the main MCU side. We apologize for any inconvenience caused.
By adjusting the pull-up resistor value in the circuit based on the I2C specifications of the main MCU, communication is now functioning properly.
Thank you for your support, and we apologize for the confusion.
