Abstract: Disclosed herein are aspects for configuring a port in an integrated circuit using a configuration state machine. An example aspect begins by determining a current state of internal pull-up and pull-down resistors of the port. The aspect then modifies resistance characteristics of the resistors from the current state. These characteristics indicate a strap configuration of a circuitry connected to the port. The aspect determines a state result based on the strap configuration and the current state. The aspect transitions to a next state based on the state result. The aspect continues by modifying resistance characteristics of the resistors from the next state, indicating a second strap configuration. A second state result is then determined based on the second strap configuration and the next state. The aspect then transitions to a resultant terminal state based on the next state and configures the port to operate in accordance with a port configuration.
