Abstract

A configurable device includes a non-volatile memory such as an electronically programmable read only memory (EPROM), a volatile memory, a protocol engine and a controller. The EPROM stores a default configuration for the device. The default configuration is transferred to the volatile memory and is stored as an alterable configuration upon application of power. The protocol engine exchanges messages with a message-based bus, such as a controller area network (CAN) bus. The controller communicates with the memory and the protocol engine to receive messages and act on the received messages based on the alterable configuration. The messages include configuration messages that cause the control logic to overwrite the alterable configuration based on a received configuration message.
