*1 : When the TPBIAS supply is Off, the maximum value with cable connected is 0.4 V, and when the cable is not
connected the maximum output voltage is VDD.
* 2 : Electrical potential created between TPA and TPB pins.
*3 : Electrical potential created between TPBIAS and TPA/B pins
*4 : At a point midway between the TPB/TPB# pins.
*5 : Cable supply voltage (VP) : voltage before division by 510 kΩ to 91 kΩ resistance
*6 : VIT+ is the voltage before cable disconnection is detected. VIT- is the voltage after cable connection is detected.
