Modes of Operation

The Thermal sensors have two usages when enabled:

  1. One use is to provide the temperature of the Processor in units of 1 oC. There is a 8 bit field for the temperature, with a theoretical range from –128 oC to +127 oC. Practically the operational range for the system is between -40 oC and 125 oC.
  2. The second use is to allow programmed trip points to cause alerts to SW or in the extreme case shutdown. Temperature may be provided without having any SW alerts set.

There are two thermal alert capabilities. One is for the catastrophic event (thermal runaway) which results in an immediate system power down (S5 state). The other alert provides an indication to the platform that a particular temperature has been caused. This second alert needs to be routed to SMI or SCI based on SW programming.
