Controller area network module adjusting arrangement for controller area network system, has controller to cooperate with oscillator that produces different frequencies depending on commands from microprocessor, in iterative operating mode

摘要

The arrangement has an oscillator (211) to produce a number of different frequencies depending on control commands from a microprocessor (205). A controller area network (CAN) controller (CC1) is provided to receive the frequencies and connected to a bus connection through a transceiver. The controller cooperates with the oscillator in an iterative operating mode. The microprocessor indicates whether a detected level or level transit represents an error frame or error flag using information about the operating mode of a CAN system and the frequencies.
