11. PLUG AND PLAY CONFIGURATION
The W83627SF uses Compatible PNP protocol to access configuration registers for setting up
different types of configurations. In W83627SF, there are twelve Logical Devices (from Logical Device
0 to Logical Device C with the exception of logical device 4 for backward compatibility) which
correspond to eleven individual functions: FDC (logical device 0), PRT (logical device 1), UART A
(logical device 2), UART B (logical device 3), KBC (logical device 5), CIR (Consumer IR, logical device
6), GP1 (logical device 7), GP2 (logical device 8), GP3 and GP4 (logical device 9), ACPI ((logical
device A), Smart Card interface (logical device B), and GP5, GP6, and GP7 (logical device C). Each
Logical Device has its own configuration registers (above CR30). Host can access those registers by
writing an appropriate logical device number into logical device select register at CR07.
