Abstract
A chip configured with pin-strapping includes a configuration pin coupled to a resistor, the resistor coupled a configuration circuit configured to provide a threshold voltage at a sense time interval. A configuration vector may be determined by driving the configuration pin with high impedance, and sampling the configuration pin at sense time intervals such that the configuration vector corresponds to the time interval at which a threshold voltage is reached.
