Abstract
According to the present invention, a device and method accomplish in-line serial programming of a default configuration into a configurable device for connection to a message-based network. The configurable device includes an input/output unit, an electrically programmable read only memory (EPROM), programming logic and a protocol engine for exchanging messages with a message-based bus based on the default configuration. The input/output unit includes pins and logic for configuring a portion of the pins to operate in both a normal mode and as a clock pin, a data pin and a program pin in a programming mode. The electrically programmable read only memory (EPROM) stores a default configuration for the configurable device. The programming logic is coupled to the input/output unit. It receives signals from the data, clock and program pins and determines data and commands based on the signals. The programming logic also executes the commands to program the data, which comprises the default configuration, into the EPROM.
