Description
66 MHz Capable: This read-only bit indicates whether this device is capable of running at 66 MHz.
0 — 33 MHz
1 — 66 MHz
Capabilities List: This read-only bit indicates whether this device implements the pointer for a new
capabilities linked list at offset 34h.
0 — No new capabilities linked list is available.
1 — The value read at offset 34h is a pointer in configuration space to a linked list of new capabilities.

This 1-byte read-only register indicates a device-specific revision identifier. The value is
chosen by the vendor. This field is a vendor-defined extension of the device ID. The
Revision ID register bit description is given in
Class Code is a 24-bit read-only register used to identify the generic function of the
device, and in some cases, a specific register-level programming interface.
shows the bit allocation of the register.
The Class Code register is divided into three byte-size fields. The upper byte is a base
class code that broadly classifies the type of function the device performs. The middle
byte is a sub-class code that identifies more specifically the function of the device. The
lower byte identifies a specific register-level programming interface, if any, so that
device-independent software can interact with the device.
