Internal Thermal Hardware Throttling Enable Bit
(ITHTE):
This bit is a master enable for internal thermal sensor-based
hardware throttling
0 Hardware actions via the internal thermal sensor are
disabled.
1 Hardware actions via the internal thermal sensor are
enabled.
Reserved
This bit determines what temperature zones will enable
automatic throttling. This register applies to internal thermal
sensor throttling. Lockable by bit0 of this register.
See also the throttling registers in PCI configuration space
Device 0 which is used to enable or disable throttling
0 = Reserved
1 = Hot and Catastrophic.
Halt on Catastrophic (HOC):
When this bit is set, THRMTRIP# is asserted on catastrophic
trip to bring the platform down. A system reboot is required to
bring the system out of a halt from the thermal sensor. Once
the Catastrophic trip point is reached, THRMTRIP# will stay
asserted even if the catastrophic trip deasserts before the
platform is shut down.
