PMU Signals
PMU_WAKE_B/
GPIO_SUS8
I
CMOS_V3P3
1
20K, PU
V3P3A
PCI Express* Wake-up Event: 
(active low). Open-Drain input 
signal that is asserted by a 
PCI Express port indicating it 
wants to wake-up the system. 
This is a single signal, named 
WAKE# by the PCI Express 
specification that can be 
driven by any of the PCI 
Express devices implemented 
on the platform board. The 
device indicating the wake-up 
drives this signal low. If the 
PMU_WAKE_B interface is not 
used, the signal can be used 
as GPIO SUS Port 8. 
PMU_PWRBTN_B/
GPIO_SUS9
I
CMOS_V3P3
1
20K, PU
V3P3A
Causes SMI# or SCI to 
indicate to the system request 
to go to a sleep state. If the 
system is in the S5 (Soft-Off) 
state, it causes a wake event. 
If PWRBTNB is pressed for 
more than 4 seconds, it 
causes an unconditional 
transition (power button 
override) to the S5 state. If 
the PMU_PWRBTN_B interface 
is not used, the signal can be 
used as GPIO SUS Port 9. 
PMU_RESETBUTTON_B/
GPIOS_30
I
CMOS_V3P3
1
20K, PU
V3P3S
This pin forces a reset after 
being debounced. If the 
PMU_RESETBUTTON_B 
interface is not used, the 
signals can be used as GPIO 
Port 30. 
PMU_PLTRST_B
O
CMOS_V3P3
1
V3P3A
Platform Reset; The SoC 
asserts PLTRST_B as the main 
SoC platform reset.
SUS_STAT_B/
GPIO_SUS10
O
CMOS_V3P3
1
V3P3A
This signal is asserted by the 
SoC to indicate that the 
system is entering a low-
power state soon. This can be 
monitored by devices with 
memory that need to switch 
from normal refresh to 
suspend refresh mode. It can 
also be used by other 
peripherals as an indication 
that the devices should isolate 
the outputs that may be going 
to powered-off planes. If the 
SUS_STAT_B interface is not 
used, the signal can be used 
as GPIO SUS Port 10.
