Voltage Regulator HI / LO (for Mobile only):
This ping is used to select an appropriate VID for
voltage regulator.
A low level indicates the Battery Optimal mode. A high
level indicates the Maximum Performance mode.
LO_HI# (for Mobile only):
This pin is connected to the processor. A high level
indicates the Battery Optimal mode. A low level
indicates the Maximum Performance mode.
VGATEM# (for Mobile only):
Output pin, it is used to mask the PWRGOOD of
processor core voltage regulator.
RTC32KHz output: (Mobile only)
Support RTC32KHz clock output in S0~S5.
Thermal Alarm2: (GTL level)
When a low active signal inputs, it will assert a
SMI#/SCI# event.
GPIO OFF: (GTL level)
When a low level signal inputs, it will turn off the
system. Then, the system can only be woken up again by
PWRBTN#.

Battery Power OK:
When the internal RTC is enabled, this signal is used to
indicate that the power of RTC well is stable. It is also
used to reset the logic in RTC well. If the internal
RTC is disabled, this pin should be tied low.
RTC 32.768 KHz Input:
When internal RTC is enabled, this pin provides the
32.768 KHz clock signal from external crystal or
oscillator.
RTC 32.768 KHz Output:
When internal RTC is enabled, this pin should be
connected with the other end of the 32.768 KHz crystal
or left unconnected if an external oscillator is used.
Main Power OK:
A high-level input to this signal indicates the power
being supplied to the system is in stable operating state.
During the period of PWROK being low, PCIRST# will
all be asserted until after PWROK goes high for 12 ms.
