20 Interfaces
55 Not Connected 56 RSVD
57 GND 58 GND
59 HDA_SYNC (Serial Bus Audio
Synchronization.) 60 SMB_CLK (Clock line of System
Management Bus.)
61 HDA_RST#(HD Audio/AC'97 Codec
Reset.) 62 SMB_DAT (Data line of System
Management Bus.)
63 HDA_BITCLK (HD Audio/AC'97 24 MHz
Serial Bit Clock from Codec) 64 SMB_ALERT# (System Management Bus
Alert input. This signal may be driven low by
SMB devices to signal an event on the SM
Bus.)
65 HDA_SDI (HD Audio/AC'97 Serial Data
Input from Codec) 66 GPO_I2C_CLK (General Purpose I²C bus
#0 clock line.)
67 HDA_SDO (HD Audio/AC'97 Serial Data
Output to Codec) 68 GPO_I2C_DAT (General Purpose I²C bus
#0 data line.)
69 THRM# (Thermal Alarm active low signal
generated by the external hardware to
indicate an over temperature situation.
This signal can be used to initiate thermal
throttling.) 70 WDTRIG# (Watchdog trigger signal. This
signal restarts the watchdog timer of the
Qseven module on the falling edge of a low
active pulse.)
71 THRMTRIP# (Thermal Trip indicates an
overheating condition of the processor. If
'THRMTRIP#' goes active, the system
immediately transitions to the S5 State
[Soft Off].)
72 WDOUT (Watchdog event indicator. High
active output used for signaling a missing
watchdog trigger. Will be deasserted by
software, system reset or a system power
down.)
73 GND 74 GND
75 USB_SSTX0- [USB 3.0] (Multiplexed with
transmit signal differential pairs for the
Superspeed USB data path.) 76 USB_SSRX0- [USB 3.0] (Receive signal
differential pair for the Superspeed USB
data path.)
77 US [USB 3.0] (Multiplexed
with transmit signal differential pairs for
the Superspeed USB data path.) 78 US [USB 3.0] (Receive signal
differential pair for the Superspeed USB
data path.)
79 USB_6_7_OC# (Over current detect input
4. This pin is used to monitor the USB
power over current of the USB Ports 6
and 7.) 80 USB_4_5_OC# (Over current detect input
3. This pin is used to monitor the USB
power over current of the USB Ports 4 and
5.)
81 USB_P5- (Universal Serial Bus Port 5
differential pair.) 82 USB_P4- (Universal Serial Bus Port 4
differential pair.)
83 (Universal Serial Bus Port 5
differential pair.) 84 (Universal Serial Bus Port 4
differential pair.)
85 USB_2_3_OC# (Over current detect input
2. This pin is used to monitor the
USB power over current of the USB Ports
2 and 3.) 86 USB_0_1_OC# (Over current detect input
1. This pin is used to monitor the USB
power over current of the USB Ports 0 and
1.)
87 USB_P3- (Universal Serial Bus Port 3
differential pair.) 88 USB_P2- (Universal Serial Bus Port 2
differential pair.)
89 (Universal Serial Bus Port 3
differential pair.) 90 (Universal Serial Bus Port 2
differential pair.)
