A resistor-programmable device generates pulses counted by a counter. The counter's output controls a drive signal generator, such as an adjustable current source. The drive signal generator generates a drive signal (such as a current), which leads to the creation of a sense signal (such as a voltage) using a resistance. The resistance can have one of a set of specified values or fall within one of a set of specified windows. The resistor-programmable device can convert the resistance value into a digital value, which can be used to set a sensor trip point threshold or some other parameter. The digital or parameter value is independent of changes in the resistance that are within a specified tolerance. For instance, the same parameter value could be selected even when the resistance varies within some tolerance (such as 1%) as the resistor-programmable device can determine the window in which the resistance falls.
