Description
SATA_GP[0]
I
V1P8S
Serial ATA 0 General Purpose:
 This is an input pin which can be configured as an 
interlock switch or as a general purpose I/O, depending on the platform. When used 
as an interlock switch status indication, this signal should be driven to ‘0’ to indicate 
that the switch is closed, and to ‘1’ to indicate that the switch is open.
SATA_GP[1]
I
V1P8S
Serial ATA 1 General Purpose:
 Same as above.
SATA_LED#
O
V1P8S
Serial ATA LED: 
This is an open-collector output pin driven during SATA command 
activity. It is to be connected to external circuitry that can provide the current to 
drive a platform LED. When active, the LED is on. When tristated, the LED is off.
SATA_TXP[1:0]
SATA_TXN[1:0]
O
VPCIESATA
Serial ATA Port 1 and 0: 
These are outbound high-speed differential signals to Port 
1 and 0.
SATA_RXP[1:0]
SATA_RXN[1:0]
I
VPCIESATA
Serial ATA Port 1 and 0: 
These are inbound high-speed differential signals to Port 1 
and 0.
SATA_DEVSLP[1:0]
I/O
V1P8S
These pins are used for hardware DEVSLP enabling.
SATA_DEVSLP[0] is multiplexed with SATA_GPI[1], MMC1_RST#.
SATA_DEVSLP[1] is multiplexed with LPE_I2S2_CLK.
SATA_RCOMP_P
SATA_RCOMP_N
O
These pins are used to connect the external resistors used for Rcomp. Please contact 
your Intel representative for details.
