For public disclosure
Configuration register access uses a banked logical device method to facilitate standard
plug-and-play software. Each functional block is assigned a separate logical device
number. For index range 0x00-0x2F, the data port accesses map into the general device
configuration registers. One of these registers is the logical device number register. For
index range 0x30-0xFF, the data port accesses map into the configuration registers of the
logical device pointed to by the logical device number register.
