3 Main Architectural Features
3.1 T8110L Architecture
The T8110L includes all of the clocking and standard switching functions found on previous Ambassador devices,
plus additional functionalities that are described in the following sections. The T8110L interfaces to a controller via
a standard microprocessor interface which is described in Section 4. Note that the full version of the device, the
T8110, contains both microprocessor and PCI interfaces, allowing the device to attach directly to a PCI bus. The
T8110L and T8110 are pin compatible.
