Summary:A method for controlling a configuration in an integrated circuit device with at least one controllable input/output port having a data output driver, a data input driver, a controllable pull-up resistor, a controllable pull-down resistor, each connected with an external pin of the integrated circuit device, has the steps of: enabling only the pull-up resistor and reading the associated input through the data input driver as a first bit; enabling only the pull-down resistor and reading the associated input through the data input driver as a second bit; tri-stating the first port and reading the associated input through the data input driver as another bit; encoding a value from the read bits; and determining a firmware operation form the encoded value.
