Tool/software:
The customer pulls the I2C signal from the CPU to the redriver IC and issues instructions to the IC through I2C.
But when the device is plugged in after setting, the values in the Registers will be cleared and become incorrect.
Is there any situation that would cause the redriver IC to behave like reset?
The most important thing is that if the positions of offset 0A and 0C are changed, it will not be able to switch to the DP function.
After powering on, the device is not plugged in, and the offset settings are what we want.
Once the USB3.0 flash drive is plugged in, the value read by I2C changes.
