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
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-
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.
