2.19.4 MEM_TRML_TEMPERATURE_REPORT—Memory
Thermal Temperature Report Register
This register is used to report the thermal status of the memory. The channel max
temperature field is used to report the maximal temperature of all ranks.
2.19.5 MEM_TRML_INTERRUPT—Memory Thermal
Interrupt Register
Hardware uses this information to determine whether a memory thermal interrupt is to
be generated or not.
