Description
Version
These bits define the current version of the backplane controller. If revisions are
required, these bits change to reflect the latest version of the device. Generally,
changes to bits 3:0 reflect a minor revision, and changes to bits 7:4 reflect a
major revision or different device type. Firmware should check this register to
determine the current capabilities of the device.
