Port 1 Detect Voltage Difference Register - Software reads this value using tps_GetDetectVoltageDifference()
Hardware - Command 68h; 2 data byte (LSB followed by MSB); read only
Port 2 Detect Voltage Difference Register
Hardware - Command 6Ah; 2 data byte (LSB followed by MSB); read only
Port 3 Detect Voltage Difference Register
Hardware - Command 6Ch; 2 data byte (LSB followed by MSB); read only
Port 4 Detect Voltage Difference Register
Hardware - Command 6Eh; 2 data byte (LSB followed by MSB); read only
This register is used to determine the presence of a legacy PD by measuring the PD input capacitance on the PI. A charge is injected into the PI and the resulting voltage differnce is reported. The resulting 12-bit data conversion has an LSB of 4.884 mV, and is only valid if the status on the port is VDS_STATUS_VALID_MEASUREMENT.
