Description
SATA_GP[0]
I
CMOS1.8
Serial ATA 0 General Purpose: This is an input pin that 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
CMOS1.8
Serial ATA 1 General Purpose: Same as above.
SATA_LED#
O
CMOS1.8_OD
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 tri-stated, the LED is off.
SATA_TXP[1:0]
SATA_TXN[1:0]
SATA_TXN[1:0]
O
SATA
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]
SATA_RXN[1:0]
I
SATA
Serial ATA Port 1 and 0: These are inbound high-speed differential
signals to Port 1 and 0.
SATA_DEVSLP[1:0]
I/O
SATA
These pins are used for hardware DEVSLP enabling.
SATA_DEVSLP[0] is multiplexed with SATA_GPI[1], MMC1_RST#.
SATA_DEVSLP[0] is multiplexed with SATA_GPI[1], MMC1_RST#.
SATA_RCOMP_P
SATA_RCOMP_N
SATA_RCOMP_N
O
These pins are used to connect the external resistors used for
Rcomp.

Feature
Description
Native Command Queuing (NCQ)
Allows the device to reorder commands for more efficient data transfers
Auto Activate for DMA
Collapses a DMA Setup then DMA Activate sequence into a DMA Setup
only
Hot Plug Support
Allows for device detection without power being applied and ability to
connect and disconnect devices without prior notification to the system
Asynchronous Signal Recovery
Provides a recovery from a loss of signal or establishing communication
after hot plug
3 Gb/s Transfer Rate
Capable of data transfers up to 3 Gb/s
ATAPI Asynchronous Notification
A mechanism for a device to send a notification to the host that the
device requires attention
Host & Link Initiated Power
Management
Capability for the host controller or device to request Partial and
Slumber interface power states
Staggered Spin-Up
Enables the host to spin up hard drives sequentially to prevent power
load problems on boot
Command Completion Coalescing
Reduces interrupt and completion overhead by allowing a specified
number of commands to complete and then generating an interrupt to
process the commands
