Claim 8:
9. The device of claim 6, wherein the switch is a first switch, the circuit is a first circuit, the condition is a first condition, and the charging port mode determination is a first charging port mode determination, the device further comprising:
a second switch having a second switch first terminal, a second switch second terminal and a second switch common terminal, wherein the second switch first terminal is coupled to the first connector pin, and the second switch second terminal is coupled to the second connector pin;
a second circuit having a second circuit input and a second circuit output, wherein the second circuit input is coupled to the second switch common terminal, and the second circuit is configured to provide at the second circuit output a true value responsive to a voltage on the second switch common terminal being equal to or greater than 2.32V, and provide at the second circuit output a false value otherwise; and
wherein the control circuit has a third control circuit input that is coupled to the second circuit output, the first control circuit output is configured to actuate the second switch, and the control circuit is configured to make a second charging port mode determination responsive to the DCD Complete signal, by:
actuating the second switch to couple the second connector pin to the second circuit input;
determining a value of a second condition, wherein the second condition has a true value if the second circuit output is a true value, and the second condition has a false value otherwise;
actuating the second switch to couple the first connector pin to the second circuit input;
determining a value of a third condition, wherein the third condition has a true value if the second circuit output is a true value, and the third condition has a false value otherwise;
sending a third signal on the second control circuit output, wherein responsive to determining that the second and third conditions are true, the third signal is configured to indicate that the device is connected to a DCP of Divider 3/4 mode;
sending a fourth signal on the second control circuit output, wherein responsive to determining that the second condition is true and the third condition is false, the fourth signal is configured to indicate that the device is connected to a DCP of Divider 2 mode;
sending a fifth signal on the second control circuit output, wherein responsive to determining that the second condition is false and the third condition is true, the fifth signal is configured to indicate that the device is connected to a DCP of Divider 1 mode; and
making the first charging port mode determination in response to determining that the second and third conditions are false.
