Note: If accessing the Global Configuration Registers, step (a) is not required.
Note: Only two states are defined: Run and Configuration. In the Run State, the chip will

The BIOS uses these configuration ports to initialize the logical devices at POST. The
INDEX and DATA ports are only valid when the SIU is in Configuration Mode.
The INDEX and DATA ports are effective only when the chip is in the Configuration
State. When the SIU is not in the Configuration State, reads return FFh and write data
is ignored.
The device enters the Configuration State by the following contiguous sequence:
Write 80H to Configuration Port.
Write 86H to Configuration Port.
The device exits the Configuration State by the following contiguous sequence:
Write 68H to Configuration Port.
Write 08H to Configuration Port.
To program the configuration registers, the following sequence must be followed:
The system sets the logical device information and activates desired logical devices
through the INDEX and DATA ports. In configuration mode, the INDEX PORT is located
at the CONFIG PORT address and the DATA PORT is at INDEX PORT address + 1.
The desired configuration registers are accessed in two steps:
always be ready to enter the Configuration State.
1. Enter Configuration Mode.
2. Configure the Configuration Registers.
3. Exit Configuration Mode.
1. Write the index of the Logical Device Number Configuration Register (i.e., 07) to
2. Write the address of the desired configuration register within the logical device to
3. The chip returns to the RUN State.

DATA PORT.
the INDEX PORT and then write or read the configuration register through the DATA
PORT.
