  • Method and apparatus for configuring an integrated circuit
    Patent number: 8618834
    Abstract: A method and apparatus configures an integrated circuit by determining a multi-bit configuration value on a single node. The multi-bit configuration value is determined by using at least a voltage level at the single node and also by detecting a time to reach a voltage threshold level at the single node, based on a voltage ramp generation circuit. The method and apparatus also includes configuring an operation mode of a circuit in the integrated circuit based on the determined multi-bit configuration value from the single node. Multi-bit configuration values may be obtained on multiple single nodes in an integrated circuit. In one example, a voltage level is employed in addition to a time to reach a voltage threshold level whereas in another example a current level on a single node is utilized in combination with detection of a time to reach a voltage threshold level.
