I/O, OD

 Acts as an interrupt of a slave device on the 

SMBus. An external pull-up resistor is required.

If the GBE_SMBALRT_N interface is not used, the signals can be 

used as NCSI_CRS_DV Carrier Sense/Receive Data Valid (CRS/

DV).

I/O

 The SDP pins are reserved pins 

that are software programmable with write/read, input/output 

capability. These default to inputs upon power up but may have 

their direction and output values defined in the EEPROM. The SDP 

bits may be mapped to the General Purpose Interrupt bits when 

configured as inputs. SDP can be used for IEEE* 1588 standard 

interface. The SDP0_0 pin can be used as a watchdog output 

indication. If the GBE_SDP0_0 interface is not used, the signal can 

be used as GPIO SUS Port 17.

bits may be mapped to the General Purpose Interrupt bits when 

configured as inputs. SDP can be used for IEEE 1588 standard 

interface. The SDP0_1 pin can be used as a watchdog output 

indication. SFP sideband signals are not supported.

If GBE_SDP0_1 interface is not used, the signal can be used as 

GPIO SUS Port 18.

If none of the above functions are used, the signal can be used as 

NCSI_ARB_IN arbitration input.

1010: Ports 0-3 activity 
1011: Ports 0-1 activity 
If the GBE_LED[3:0] interface is not used, the signals can be used 

as GPIO SUS Port [22:19].

: Data signals to the Manageability 

Controller (MC). Pin strap to enable GbE in S5 (1’b1 to enable – 

the default). If the NCSI_RXD1 signal is not used, the signal can 

be used as GPIO SUS Port 23. Refer to 

.

I/O, OD

: Serial clock for the management channel. Can also be 

configured as an I

2

C (OD) clock. If the GBE_MDIO0_I2C_CLK 

interface is not used, the signal can be used as GPIO SUS Port 24. 

I/O, OD

: Serial data for the management channel. Can also be 

configured as I

2

C (OD) data. If the GBE_MDIO1_I2C_DATA 

interface is not used, the signal can be used as GPIO SUS Port 25. 

I/O, OD

: Serial clock for the management channel. Can also be 

configured as an I

2

C (OD) clock. If the GBE_MDIO1_I2C_CLK 

interface is not used, the signal can be used as GPIO SUS Port 26. 

If none of the above functions are used, the signal can be used as 

NCSI_TXD1 Transmit Data 1. Data signals from the MC. 

If not used, should have an external pull-up resistor.
