The signal description table has the following headings:

• Signal Name: The name of the signal/pin
• Direction: The buffer direction is either input, output, or I/O (bi-directional)
• Voltage Level: Typical operating voltage of the signal
• Power Well: SoC power well used for signal circuitry
• Function: A brief explanation of the signal functions

Output

3.3V

SUS

Signals the platform board to power down the 

Suspend (SUS) well during S5.
This signal is muxed and is used by other functions.

Output

3.3V

SUS

Signals the platform board to power down DDR VTT.
This signal is muxed and is used by other functions.

Output

3.3V

SUS

Signals the platform board to get into the S5 state 

and to power down the core well including the DRAM 

power.

Output

3.3V

SUS

Signals the platform board that the SoC has entered 

the S3 state and that the SoC core-well supplies can 

be powered down. The DRAM power must remain on

Output

3.3V

SUS

Signals the platform board to power down the 

powering to the Gigabit Ethernet PHY circuitry.
This signal is non-functional and is always 

Output

3.3V

SUS

Used as the platform board reset.

Output

3.3V

SUS

Indicates to the platform board that a low-power 

state (S5) is entered soon. The platform needs to 

work from the SUS well only.
This signal is muxed and is used by other functions.

Output

3.3V

SUS

Suspend clock output. Frequency of 32.768 kHz 

originating from the Real Time Clock (RTC) clock 

circuitry.
This signal is muxed and is used by other functions.

Input

3.3V

SUS

Wake signal from the PCI Express* interface.
This signal is muxed and is used by other functions.

Input

3.3V

SUS

Power button input.
This signal is muxed and is used by other functions.

Input

3.3V

Core

Reset button input.
This signal is muxed and is used by other functions.
