INTRUDER#

I

Intruder Detect: This signal can be set to disable the system if box detected open.

GPP_​C4 /SML0DATA

I/OD

System Management Link 0 Data: SMBus link to external PHY.

External Pull-up resistor required.

GPP_​C3 / SML0CLK

I/OD

System Management Link 0 Clock

External Pull-up resistor required.

GPP_​C5 / SML0ALERT#

I/OD

System Management 0 Alert: Alert for the SMBus controller to optional Embedded Controller or BMC.

External Pull-up resistor required.

GPP_​C6 / SML1CLK

I/OD

System Management Link 1 Clock: SMBus link to optional Embedded Controller or BMC. External Pull-up resistor required.

GPP_​C7 / SML1DATA

I/OD

System Management Link 1 Data: SMBus link to optional Embedded Controller or BMC. External Pull-up resistor required.

GPP_​B23 / SML1ALERT# / PCHHOT# / GSPI1_​CS1#

I/OD

System Management 1 Alert: Alert for the SMBus controller to optional Embedded Controller or BMC. A soft-strap determines the native function SML1ALERT# or PCHHOT# usage.

This is NOT the right Alert pin for USB-C* usage.

External Pull-up resistor is required on this pin.

GPP_​B11 / PMCALERT#

I/OD

USB Type-C* PD Controller / Re-timer Alert: Alert for the SMLink1 Bus controller to all USB Type-C* PD Controllers, mandatory requirement for integrated USB-C* feature to work.

External Pull-up resistor is required on this pin.

GPP_​B23 / SML1ALERT# / PCHHOT# / GSPI1_​CS1#

OD

This signal is used to indicate a PCH temperature out of bounds condition to an external EC.

An external pull-up resistor is required on this signal.SML1ALERT# is IOD, PCHHOT# is OD.
