Abstract
Methods and apparatus associated with a plurality of serial devices designed to communicate with a bus master in either a daisy chain or a normal configuration are provided. One method includes the step of serially providing a command sequence having a channel identifier to a given device of a plurality of daisy chained devices. The channel identifier is modified as it passes thru each daisy chained device. A specific device is identified or enabled when the channel identifier it receives matches a pre-determined value.
