1.1 Terminology
Term Description
ACPI Advanced Configuration and Power Interface
ADD2
Advanced Digital Display 2. An interface specification that accepts serial DVO inputs and
translates them into different display outputs such as DVO, TVOUT, and LVDS.
Cold Reset
Full reset is when PWROK is de-asserted and all system rails except VCCRTC are powered
down

DDR2 A second-generation Double Data Rate SDRAM memory technology.
DVI
Digital Video Interface. DVI is a specification that defines the connector and interface for
digital displays.
EIOB Electronic In/Out Board
HDMI
High Definition Multimedia Interface. HDMI supports standard, enhanced, or high-definition
video, plus multi-channel digital audio on a single cable. HDMI transmits all Advanced
Television Systems Committee (ATSC) HDTV standards and supports 8-channel digital audio,
with bandwidth to spare for future requirements and enhancements (additional details
available at http://www.hdmi.org/).

Thermal
Monitor 2
Intel
®
Thermal Monitor 2 is a feature of the Intel
®
Atom™ Processor E6xx Series. The Intel
®
Thermal Monitor 2 contains the Enhanced Thermal Control Circuit (TCC). When the Monitor is
enabled and active due to the die temperature reaching the pre-determined activation
temperature, the Enhanced TCC attempts to cool the processor by first reducing the core to a
specific bus ratio, then stepping down the VID.

Monitor
Intel
®
Thermal Monitor is a feature of the Intel
®
Atom™ Processor E6xx Series. The Intel
®
Thermal Monitor contains the Thermal Control Circuit (TCC). When the Monitor is enabled and
active due to the die temperature reaching the pre-determined activation temperature, the
TCC attempts to cool the processor by stopping the processor clocks for a period of time and
then allowing them to run full speed for a period of time (duty cycle ~30% – 50%) until the
processor temperature drops below the activation temperature.
LCD Liquid Crystal Display
LVDS
Low Voltage Differential Signaling. LVDS is a high speed, low power data transmission
standard used for display connections to LCD panels.
MPEG Moving Picture Experts Group
MSI
Message Signaled Interrupt. MSI is a transaction initiated outside the host, conveying
interrupt information to the receiving agent through the same path that normally carries read
and write commands.
MSR
Model Specific Register, as the name implies, is model-specific and may change from
processor model number (n) to processor model number (n+1). An MSR is accessed by
setting ECX to the register number and executing either the RDMSR or WRMSR instruction.
The RDMSR instruction will place the 64 bits of the MSR in the EDX: EAX register pair. The
WRMSR writes the contents of the EDX: EAX register pair into the MSR.
PCI Express*
PCI Express* (PCIe*) is a high-speed serial interface. The PCIe* configuration is software-
compatible with the existing PCI specifications.
Rank
A unit of DRAM corresponding to a number of SDRAM devices in parallel such that a full 64-bit
data bus is formed.
