GbE SMBus Alert:
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
GbE Port 0 SW Defined Pin 0:
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.
I/O
GbE Port 0 SW Defined Pin 1:
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_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.

1000: Ports 0-3 ink up
1001: Ports 0-1 link up
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].

NCSI Receive Data 1
: 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
Gigabit Ethernet Controller Management Channel 0 Clock
(out)
: 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
Gigabit Ethernet Controller Management Channel 0 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 25.
I/O, OD
Gigabit Ethernet Controller Management Channel 1 Clock
(out)
: 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.
Note:
If not used, should have an external pull-up resistor.
