Abstract:
1. A device, comprising: an interface controller capable of controlling communication over a communication link, the communication link comprising a clock signal line, a plurality of binary control signal lines, and a plurality of data lines, the interface controller dynamically configurable to a selected one of a plurality of bus width values and operable to send a signal over the communication link to configure a second interface controller to the selected bus width value, each bus width value identifying a number of data lines over which data are to be transmitted; wherein the selected bus width value represents a current bus width, wherein a direction of transmission over each data line is selectable, and wherein data are transmitted over the communication link within a transaction comprising a command transmission phase and a data transmission phase; wherein the interface controller is further capable of at least one of: transmitting an interface status signal over at least one of the binary signal lines and receiving the interface status signal over at least one of the binary signal lines.
