TEMP_AVG_INTRVL (temp_avg_intrvl):

Temperature data is averaged over this period. At the end of averaging period 

(ms) , averaging process starts again. 0x1 - 0xFF = Averaging data is read via 

TEMPDIMM STATUSREGISTER (Byte 1/2) as well as used for generating 

hysteresis based interrupts.
00 = Instantaneous Data (not averaged) is read via TEMPDIMM 

STATUSREGISTER (Byte 1/2) as well as used for generating hysteresis based 

interrupts.
Note: Cpu does not support temp averaging.

Initiate 2X refresh on TEMPLO (ev_2x_ref_templo_en):

Initiate 2X refresh on TEMPLO

DIMM with extended temperature range capability will need double refresh rate 

in order to avoid data lost when DIMM temperature is above 85C but below 

95C.

Warning: If the 2x refresh is disable with extended temperature range DIMM 

configuration, system cooling and power thermal throttling scheme must 

guarantee the DIMM temperature will not exceed 85C.
