SUS Well GPIO_1: 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 Manageability 
Controller (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 
.

token output pin.
Note:
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.
