Would you please advice of concern point set to DISCONADJ = 011(587.5mV).

[ Background of the question ]

Customer would like to set USB PHY Transmitter Control Register of (USBPHYx_TXn) the "D_CAL" to 011 for EYE pattern quality impruvement.,

It would detect problems Disconnection in combination with a specific device has occurred in its influence.

However, in order to be avoided problems by increasing the threshold of detection Disconnect from 575mV to 587.5mV, we have to consider the configuration changes.

Thanks,
