6. CONFIGURATION REGISTER
6.1 Plug and Play Configuration
The W83697UF uses Compatible PNP protocol to access configuration registers for setting up
different types of configurations.
Device 0 to Logical Device B with the exception of logical device 4 for backward compatibility) which
correspond to eleven individual functions: FDC (logical device 0), PRT (logical device 1), UART1
(logical device 2), UART2 (logical device 3), CIR (Consumer IR, logical device 6), GPIO1 (logical
device 7), GPIO5(logical device 8),GPIO2 ~GPIO4(logical device 9), ACPI ((logical device A), and
Hardware monitor (logical device B). 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 CR7.
