Abstract

A command string is sent from an operating system to a microcontroller coupled to one or more I.sup.2 C buses. Such a command string may instruct the microcontroller to perform a read or write operation with respect to a bus device designated within the command string. The presence of the bus device may be new and the microcontroller unaware of such a presence. Data may be read from the main system to the particular bus device through the microcontroller, or data may be read from the bus device through the microcontroller back to the main system.
