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 27. 

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

NCSI_TXD0 Transmit Data 0. Data signals from the MC. 

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

I/O

 General purpose Customer I/O. If GPIO_SUS1 

is not used, the signal can be used as NCSI_RXD0 Receive Data 0 

signal to the MC. 
This pin is also a pin-strap input. If sensed low, the 2.5-GbE 

capability, if available, is disabled. This pin must be sampled high 

for the 2.5-GbE capability to function. 
This pin is temporarily pulled-down internally during the sample 

period. An external pull-up resistor is needed during the sample 

period to enable 2.5 GbE. Refer to 

O

: NC-SI hardware arbitration token output pin.

This pin is also a hard pin-strap. When it is a logic high at 

power-up, it indicates the NC-SI interface is to be used 

rather than the GBE_SMBus. Refer to 

.
