A device (212) that transfers data includes a destination (216), a first data source (216), a second data source (216), a connector (220), and a control system (214). The first data source (216) can have first data to send to the destination (216). The second data source (216) can have second data to send to the destination (216). The connector (220) electrically connects the data sources (216) to the destination (216). The device control system (214) is electrically connected to the sources (216) and the destination (216). The device control system (214) utilizes an arbitration progression that sequentially grants access to the connector (220) to only the data sources (216) that have data to send to the destination (216). The device control system (214) can evaluate a first data rate of the first data and a second data rate of the second data, and can grant access to the data sources (216) that have data to send to the destination (216). Further, the device control system (214) can utilize digital hysteresis to control the granting of access to the data sources (216) that have data to send to the destination (216). This can enhance the efficiency of the device (212) with minimal, if any, increase in size or complexity.
