Data exchanging method for e.g. single wire bus system, involves issuing release of execution of potential of action by master before notification of request by slave, when defined conditions are fulfilled

摘要

The method involves connecting a master (14) and a slave (16) to a single wire bus (12) of a bus system (10). The slave notifies an action to be developed to the master on externally received request. The master releases the execution of the action during fulfillment of defined conditions. The master issues the release of execution of the potential of the action before the notification of the request by the slave, when the defined conditions are fulfilled, where the action is requested externally.
