ICH8ME Serial Peripheral Interface (SPI) BIOS
The 4-pin SPI is connected to an SPI BIOS chip. A licensed copy of AMI BIOS is
preinstalled on the SPI BIOS chip. A master-slave protocol is used for communication on
the SPI bus. The slave is connected to the Intel® ICH8ME and is implemented as a
tri-state bus.

ICH8ME USB Controller
Up to eight high-speed, full-speed or low-speed USB devices are supported by the
ICH8ME on the PCISA-9652. High-speed USB 2.0, with data transfers of up to 480MB/s,
is enabled with the ICH8ME integrated Enhanced Host Controller Interface (EHCI)
compliant host controller. USB full-speed and low-speed signaling is supported by the
ICH8ME integrated Universal Host Controller Interface (UHCI) controllers.
Six of the eight USB ports implemented on the PCISA-9652 are connected to two internal
connectors and two external connectors. See Figure 2-11.
