... GND Float Float Float * Represents codes without a defined output voltage as specified in Intel specifications. The LTC1706-81 interprets these codes as a valid input and produces an output voltage as follows: (11111 program output voltages higher than 2.05V, the range VID0 OUTPUT bit should be set high (VID4 = High). In this range, when the four VID inputs are low, the output is 3 ...
