Abstract
An electronic device has terminals for interfacing internal signals to other electronic devices. Each terminal is electrically coupled to a terminal driver and a terminal control circuit for receiving a terminal configuration defining the properties and multiplexing of the terminal. The actual configuration of the terminal driver is set according to the terminal configuration. The device has at least one terminal checker arranged for comparing the actual configuration to at least one check configuration, the check configuration defining a configuration of the terminal driver that is either allowed or not allowed, and for, when said comparing indicates a not allowed configuration, setting the actual configuration to a default configuration. Advantageously safe operation of the device in a system is achieved by monitoring the configuration of the multiplexed terminals, and switching to a default configuration when in error.
