Datasheet 59
Signal Description
SATA3RXP
SATA3RXN
I
Serial ATA 3 Differential Receive Pair: These are inbound high-
speed differential signals from Port 3.
In compatible mode, SATA Port 3 is the secondary slave of SATA
Controller 1
Supports up to 3 Gb/s and 1.5 Gb/s.
NOTE: SATA Port 3 may not be available in all PCH SKUs.
SATA4TXP
SATA4TXN
O
Serial ATA 4 Differential Transmit Pair: These are outbound
high-speed differential signals to Port 4.
In compatible mode, SATA Port 4 is the primary master of SATA
Controller 2.
Supports up to 3 Gb/s and 1.5 Gb/s.
SATA4RXP
SATA4RXN
I
Serial ATA 4 Differential Receive Pair: These are inbound high-
speed differential signals from Port 4.
In compatible mode, SATA Port 4 is the primary master of SATA
Controller 2.
Supports up to 3 Gb/s and 1.5 Gb/s.
SATA5TXP
SATA5TXN
O
Serial ATA 5 Differential Transmit Pair: These are outbound
high-speed differential signals to Port 5.
In compatible mode, SATA Port 5 is the secondary master of SATA
Controller 2.
Supports up to 3 Gb/s and 1.5 Gb/s.
SATA5RXP
SATA5RXN
I
Serial ATA 5 Differential Receive Pair: These are inbound high-
speed differential signals from Port 5.
In compatible mode, SATA Port 5 is the secondary master of SATA
Controller 2.
Supports up to 3 Gb/s and 1.5 Gb/s.
SATAICOMPO O
Serial ATA Compensation Output: Connected to an external
precision resistor to VccCore. Must be connected to SATAICOMPI
on the board.
SATAICOMPI I
Serial ATA Compensation Input: Connected to SATAICOMPO on
the board.
SATA0GP /
GPIO21
I
Serial ATA 0 General Purpose: This is an input pin which can be
configured as an interlock switch corresponding to SATA Port 0.
When used as an interlock switch status indication, this signal
should be drive to ‘0’ to indicate that the switch is closed and to ‘1’
to indicate that the switch is open.
If interlock switches are not required, this pin can be configured as
GPIO21.
SATA1GP /
GPIO19
I
Serial ATA 1 General Purpose: Same function as SATA0GP,
except for SATA Port 1.
If interlock switches are not required, this pin can be configured as
GPIO19.
SATA2GP /
GPIO36
I
Serial ATA 2 General Purpose:
Same function as SATA0GP,
except for SATA Port 2.
If interlock switches are not required, this pin can be configured as
GPIO36.
