The signal description table has the following headings:

• Signal Name: The name of the signal/pin
• Direction: The buffer direction is either input, output, or I/O (bi-directional)
• Type: The buffer type found in 

• Description: A brief explanation of the signal function

Signals for SATA3 interface are identical to SATA2 interface. The only exception is 

SATA_TX and SATA_RX signals are 1:0, since only two ports are in the SATA3 controller.

I/O OD

 This is an input pin which is 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 is 

driven to 0 to indicate that the switch is closed, and to 1 to indicate that 

the switch is open.

OD

This is an open-collector output pin driven during SATA 

command activity. This pin is to be connected to external circuitry that 

provides the current to drive a platform LED. When active, the LED is on. 

When tri-stated, the LED is off.

O/Differential

These are outbound high-speed differential 

signals to Ports 0, 1, 2 and 3.

I/Differential

These are inbound high-speed differential signals 

to Ports 0, 1, 2 and 3.
