TUSB2E221: I2C config change timing

Koyo Asaishi

Part Number: TUSB2E221


Hello team

Is there non-allowable timing that I2C config can be change? Can I2C registers be changed anytime? For example, the registers should be changed while USB communication isn't being doing.

Best regards

    Hi Koyo,

    The only requirement should be that I2C communication should not be sent until the TUSB2E221 is powered and stable. Otherwise, I2C should be available at all times, regardless of whether there is USB communication or not.

    Thanks,

    Ryan
