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. In W83697UF, there are eleven Logical Devices (from Logical

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.
