Abstract
In one aspect the invention relates to a method of selecting a state from a plurality of states using a program pin. The method includes connecting the program pin to one of a first current source and a second current source, in response to a first voltage applied to the program pin, to thereby generate a second voltage at the program pin, and selecting a state from the plurality of states in response to the first and second voltages. In another embodiment, the method includes determining whether the first voltage exceeds a first reference voltage. In another embodiment, the method includes connecting the program pin to the first current source if the first voltage does not exceed the first reference voltage, and connecting the program pin to the second current source if the first voltage exceeds the first reference voltage.
