MEM_TRML_THRESHOLDS_CONFIG—Memory
Thermal Thresholds Configuration Register
This register is used to describe the thresholds of the memory thermal management in
the memory controller. The warm threshold defines when self-refresh is at double data
rate. Throttling can also be applied at this threshold based on the configuration in the
memory controller. The hot threshold defines the threshold at which severe thermal
throttling will occur. Self Refresh is also at double rate during a hot condition.
