Policy Lock-Down Bit — R/W.
0 = This register can be programmed and modified.
1 = Prevents writes to this register and TSTTP.bits [31:16] (offset 04h).
NOTE: TSCO.bit 7 (offset 08h) and TSLOCK.bit2 (offset 83h) must also be 1 when this
bit is set to 1.
This bit is reset to 0 by a host partitioned reset (note that CF9 warm reset is a host
partitioned reset). Writing a 0 to this bit has no effect.
Catastrophic Power-Down Enable — R/W.
When set to 1, the power management logic unconditionally transitions to the S5 state
when a catastrophic temperature is detected by the sensor.
NOTE: BIOS should set this bit to 1 to enable Catastrophic power-down.
Reserved
SMI Enable on Auxiliary2 Thermal Sensor Trip — R/W.
0 = Disables SMI# assertion for Auxiliary2 Thermal Sensor events.
1 = Enables SMI# assertions on Auxiliary2 Thermal Sensor events for either low-to-
high or high-to-low events. (Both edges are enabled by this bit.)
SMI Enable on Catastrophic Thermal Sensor Trip — R/W.
0 = Disables SMI# assertion for Catastrophic Thermal Sensor events.
1 = Enables SMI# assertions on Catastrophic Thermal Sensor events for either low-to-
high or high-to-low events. (Both edges are enabled by this bit.)
SMI Enable on Hot Thermal Sensor Trip — R/W.
0 = Disables SMI# assertion for Hot Thermal Sensor events.
1 = Enables SMI# assertions on Hot Thermal Sensor events for either low-to-high or
high-to-low events. (Both edges are enabled by this bit.)
SMI Enable on Auxiliary Thermal Sensor Trip — R/W.
0 = Disables SMI# assertion for Auxiliary Thermal Sensor events.
1 = Enables SMI# assertions on Auxiliary Thermal Sensor events for either low-to-
high or high-to-low events. (Both edges are enabled by this bit.)
