Communication device for communication after master slave communication instruction, is formed as slave instance which communicates over bus with master instance

摘要

The communication device (100) is formed as slave instance which communicates over a bus (150) with a master instance (160), where the master instance is effective and switched around the bus into a bus-suspend condition, if during a pre-determined interval no bus activity is present. Two units are provided where one unit (110) examines bus activity, and other unit (120) sends a signal by the bus, if the examining unit recognizes no bus activity during a part of the pre-determined interval. Independent claims are also included for the following: (1) a communication method (2) a computer program product.
