Claim 13:
14. The system of claim 11, 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 system further comprising:
a second switch having first and second switch terminals and a second switch common terminal, wherein the first switch terminal is coupled to the first connector pin, and the second switch 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 configured to provide at the second circuit output a true value based on 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, the third control circuit input 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, the second condition having a true value if the second circuit output is a true value, and the second condition having 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 having a false value otherwise;
sending a third signal on the second control circuit output, wherein the third signal is configured to indicate that the system is connected to a DCP of Divider 3/4 mode in response to determining that the second and third conditions are true;
sending a fourth signal on the second control circuit output, wherein the fourth signal is configured to indicate that the system is connected to a DCP of Divider 2 mode in response to determining that the second condition is true and the third condition is false;
sending a fifth signal on the second control circuit output, wherein the fifth signal is configured to indicate that the system is connected to a DCP of Divider 1 mode in response to determining that the second condition is false and the third condition is true; and
making the first charging port mode determination in response to determining that the second and third conditions are false.
