A device comprises a detector configured to detect an event, and a selector coupled to the detector and configured to generate a signal in response to a detection of an event by the detector. The signal is operable to select a set of input/output (I/O) parameters from among first and second stored sets of parameters. The device also includes a configuration module coupled to the selector. The configuration module is configured to output the selected set of I/O parameters.

Input/output parameter selection

A microcontroller has integrated monitoring capabilities for network applications. The disclosed techniques can take advantage, for example, of an unused, duplicate network controller that is present in some microcontrollers by providing selection circuitry and configuration capabilities that allow the unused, duplicate network controller to be used for the purpose of monitoring frames that are transferred between network media and another network controller residing on the microcontroller. The monitored frames can then be used, for example, for debugging or other purposes, such as statistical analyzes or security enhancements.
