Abstract
An invalid configuration detection resource for identifying and reporting conflicts between system resources of a microcontroller or other device is provided. Selected system registers within each resource are monitored by discrete hardware logic within the invalid configuration detection resource. For each resource, a status register provides an encoding of the configuration for that resource. The invalid configuration detection resource then compares the status registers for invalid combinations, and encodes this information in a system status register. Alternatively, the invalid configuration detection resource monitors each selected system register, independent of the resource to which it belongs. Improper combinations of registers are then encoded in a system status register. An alternative embodiment uses software to replace the discrete hardware logic with a table that specifies invalid register combinations. The invalid configuration detection resource further provides a software-controlled bit mask register.
