Signal Descriptions
I/O, OD
Gigabit Ethernet Controller Management Channel 1 Data
(T/S)
: 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.
Note:
If not used, should have an external pull-up resistor.
I/O
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 MC.
This pin is also a pin-strap input. If sensed low, the 2.5-GbE
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
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
NCSI_ARB_OUT
: NC-SI hardware arbitration 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. Refer to
