Description
31:27 RV 0h Reserved
26:24 RW 0h
TEMP_THRT_HYST: Positive going Threshold Hysteresis Value
Set to 00h if sensor does not support positive-going threshold hysteresis. This
value is subtracted from TEMP_THRT_XX to determine the point where the
asserted status for that threshold will clear.
23:16 RW 5Fh
TEMP_HI
TCase threshold at which to Initiate THRTCRIT and assert THERMTRIP# valid
range: 32–127 °C.
Note: The default value is listed in decimal.
FF = Disabled
Others = Reserved
TEMP_HI should be programmed so it is greater than TEMP_MID
15:8 RW 5Ah
TEMP_MID
TCase threshold at which to Initiate THRTHI and assert valid range: 32–127 °C.
Note: The default value is listed in decimal.
FF = Disabled
Others = Reserved
TEMP_MID should be programmed so it is less than TEMP_HI
7:0 RW 55h
TEMP_LO
TCase threshold at which to Initiate 2x refresh and/or THRTMID and initiate
Interrupt (MEMHOT#).
Note: The default value is listed in decimal.valid range: 32–127 °C.
FF = Disabled
Others = Reserved
TEMP_LO should be programmed so it is less than TEMP_MID
