ATXPG_IN, VCC (PWOK), VSB (RSMRST) and S3 signals to detect the sleep state while AC  
loss occur. One of the signal (ATXPG_IN or VCC under 2.8V or VSB under 2.8V) sinks low,  
SIO will latch the S3 signal to decide the system to be at “always on” or “always off” mode.

6.8.2 Intel Power Saving Function Deep Sleep Well (DSW)  
The F81867 supports Intel Cougar Point (CPT) Chipset timing for Sandy Bridge (Sugar Bay or Huron  
River Platform). There are 4 pins for CPT control: SUS_WARN#, SUS_ACK#, SLP_SUS# and DPWROK.  
For entering the Intel Deep Sleep Well (DSW) state, the PCH will assert SUS_WARN# (low level) and  
turn off 5VDUAL. After the level of 5VDUAL is lower than 1.05V, F81867 will assert SUS_ACK# to inform PCH  
it is ready for entering DSW. Finally, PCH will ramp down the internal VccSUS and assert SLP_SUS# to  
F81867. F81867 will turn off the 5VSB and 3VSB by ERP_CTRL0# and enter the DSW state.  
To exit DSW state, PCH will de-assert SLP_SUS#, turn on the SUS rail FETs and ramp up internal  
1.05V VccSUS. After the SUS rails voltages are up, RSMRST# will be desserted and the PCH will release  
SUS_WARN# so that the 5VDUAL will ramp up.  
Because the DSW function is controlled by the F81867 instead of controlled by the PCH directly, there  
will be more wakeup events such as LAN, KB/Mouse, GPIO0x, GPIO1x, SIO RI# wake up rather than the 3  
wakeup events (RTC, Power Button and GPIO27) for Intel DSW.
