4.5.2 Function
The VER register records version information for the PCB board as well the board
architecture. The PCB board version can change without impacting the board architecture
version, and vice versa.

4.5.4 Fields
Field
7-4 Board architecture version:
ARCH 1= V1
2= V2 (etc.)
3-0 PCB board version:
BRD 1= Rev A (or pre-release)
2= Rev B (etc.)
The ARCH field is used by QIXIS and software to handle architecture changes. The
ARCH field allows the use of a common QIXIS image across multiple board revisions, if
supported by the device.
The BRD field lets end users determine the version of the board. Software can use this
field to print board version identification. For example:
printf("Board Version: %c", (get_pixis( VER ) & 0Fh) + 'A' - 1 );
