Signal Description
| Name | Type | Description |
|---|---|---|
| INTRUDER# | I | Intruder Detect: This signal can be set to disable the system if box detected open. |
| | I/OD | System Management Link 0 Data: SMBus link to external PHY. External Pull-up resistor required. |
| | 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. |
| | I/OD | System Management Link 1 Clock: SMBus link to optional Embedded Controller or BMC. External Pull-up resistor required. |
| | I/OD | System Management Link 1 Data: SMBus link to optional Embedded Controller or BMC. External Pull-up resistor required. |
| GPP_B23 / SML1ALERT# / PCHHOT# | 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. |
| | 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# | 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. |
