Class Code (Read Only / set to 06h)

Bits 0 to 7 / Revision ID. These read only bits identify the specific device revision and are selected by

Dallas Semiconductor.

Bits 8 to 15 / Class Code Interface. These read only bits identify the sub-class interface value for the

device and are fixed at 00h. See Appendix D of PCI Local Bus Specification Revision 2.1 for details.

Bits 16 to 23 / Class Code Sub-Class. These read only bits identify the sub-class value for the device

and are fixed at 80h, which indicate "Other Bridge Device". See Appendix D of PCI Local Bus

Specification Revision 2.1 for details.

Bits 24 to 31 / Class Code Base Class. These read only bits identify the base class value for the device

and are fixed at 06h, which indicate "Bridge Devices". See Appendix D of PCI Local Bus Specification

Revision 2.1 for details.

BIST (Read Only / set to 00h)

Bits 0 to 7 / Cache Line Size. These read only bits are forced to zero.

Bits 8 to 15 / Latency Timer. These read only bits are forced to a zero by the device since the device

cannot act as a bus master.

Bits 16 to 23 / Header Type. These read only bits are forced to 80h, which indicate a multifunction

device.

Bits 24 to 31 / Built-In Self Test (BIST). These read only bits are forced to zero.
