This 24-bit, read-only register is divided into three one-
byte fields: the base class byte at location 0Bh, the
sub-class byte at 0Ah, and the programming interface
byte at 09h. The default setting for the base class is
FFh, which indicates that the device does not fit into
the thirteen base classes defined in the PCI Bus Spec-
ification. It is possible, however, through use of the
external non-volatile memory to change the value of
this register. Refer to the PCI specification for details.
