PM_EXTTS[1:0]#

External Thermal Sensor Input:
If the system temperature reaches a dangerously 
high value then this signal can be used to trigger 
the start of system memory throttling.
EXTTS1# can alternately be used to implement 
fast C4/C4E exit. See 

for details. This 

functionality is not available on EXTTS0#.
