NOTE: The SMBus I/F signals are all in the RESUME well.
NOTE: INTRUDER# is in the RTC well. The SMLINK signal is in the RESUME well.
NOTE: An external Crystal/Resistor/Capacitor circuit is required for proper operation of the

SMBus Data: External pull-up is required.
SMBus Clock: External pull-up is required.
SMBus Alert: This signal is used to wake the system or generate SMI#.
When not used for SMBALERT#, it may be used as a GPIO (GPIO[11]).
Intruder Detect: Detects if the system case has been opened. May be
set to disable the system when box is detected open.
This signal’s status is readable, so it may be used like a GPI when the
Intruder switch is not needed.
System Management Link: SMBus link to optional external system
management ASIC or LAN Controller. External pull-ups are required.
Note that SMLINK[0] corresponds to a SMBus Clock signal, and
SMLINK[1] corresponds to a SMBus Data signal.
Crystal Input 1: Connected to the 32.768 KHz crystal. When no
external crystal is used, then RTCX1 may be driven with the desired
clock rate.
Crystal Input 2: Connected to the 32.768 KHz crystal. When no
external crystal is used, then RTCX2 should be left floating.
Bias Voltage for Oscillator: Sets the proper biasing for the oscillator.
Expected voltage 200 mV.
