In one example, a method of operating a wireless communication is provided. To perform sequential reads and writes on each clock cycle, the scannable register can generate a write clock that, during the shift phase, is inverted from the clock used for functional operation. A data source subsystem can create a data source object in accordance with the overridden data source configuration, for use in creating connections to a database associated with the particular referencing partition, monitoring and diagnosing the data source object.
