ICH6M Real Time Clock
256 bytes of battery backed RAM is provided by the Motorola MC146818A real time clock
(RTC) integrated into the ICH6M. The RTC operates on a 3V battery and 32.768KHz
crystal. The RTC keeps track of the time and stores system data even when the system is
turned off.

ICH6M USB Controller Overview
Up to eight high-speed, full-speed or low-speed USB devices are supported by the ICH6M
on the 3307740. High-speed USB 2.0, with data transfers of up to 480MB/s, is enabled
with the ICH6M integrated Enhanced Host Controller Interface (EHCI) compliant host
controller. USB full-speed and low-speed signaling is supported by the ICH6M integrated
Universal Host Controller Interface (UHCI) controllers.
