Abstract
There is provided a method and apparatus for bus width negotiation. One such method includes determining a configuration of a first bond pad, the first bond pad indicating whether a host is configured to communicate with a fixed data storage device or a removable data storage device. If the first bond pad indicates the host is configured to communicate with a fixed data storage device, then the method additionally includes determining the configuration of a second bond pad. The second bond pad indicates the supported bus width of the fixed data storage device.
