Identify (05H)
This command returns a special Status Block that contains information about
the Firmware installed on the board. It can be used to determine board
compatibility and support of options (especially useful if your application
depends on certain functions to be in place on every product). The Board
Information command, discussed in a later section, returns this information plus
Unit Options setup for each target and hardware jumper settings.
The Identify command can be issued with either type of command structure.
Its primary use may be during initialization, which may require use of a Single
Command Structure (due to limitations on available memory at power-up).
