T_CRIT HYSTERESIS REGISTER
7 RTH7 This bit is unused. OK to write 1 or 0.
Remote Diode T_CRIT Hysteresis
T_CRIT stays activated until the remote diode temperature goes below [(T_CRIT
Limit)—(T_CRIT Hysteresis)].
RTH6 has a bit weight of 64°C
0x0A

RTH5 has a bit weight of 32°C
(10°C)
6:0 RTH6:RTH0
RTH4 has a bit weight of 16°C
RTH3 has a bit weight of 8°C
RTH2 has a bit weight of 4°C
RTH1 has a bit weight of 2°C
RTH0 has a bit weight of 1°C
30
HEX
REMOTE DIODE TruTherm ENABLE REGISTER
R 7:2 0x00 [Reserved] These bits are unused and always read as 0.
Remote Diode TruTherm Enable
0: TruTherm beta compensation technology is turned off. Use this mode when
30 R/W 1 1 RDTE using an MMBT3904 as a thermal diode.
1: TruTherm beta compensation technology is turned on. Use this mode when
sensing a thermal diode in an Intel processor on 45 nm or 65 nm process.
R 0 0 [Reserved] This bit is unused and always read as 0.
BF
HEX
REMOTE DIODE TEMPERATURE FILTER AND COMPARATOR MODE
R/W 7:6 00 [Reserved] These bits are unused and always write 0.
R 5:3 000 [Reserved] These bits are unused and always read as 0.
Remote Diode Temperature Filter Control
00: Filter Disabled
01: Filter Level 2 (minimal filtering, same as 10; Like LM63, LM63 Level 1 not
2:1 00 RDTF1:RDTF0 supported)
BF
10: Filter Level 2 (minimal filtering, same as 01; like LM63, LM63 Level 1 not
supported)
R/W
11: Filter Enhanced Level 2 (maximum filtering)
Comparator Mode
0: the ALERT pin functions normally.
0 0 ALT/CMP
1: the ALERT pin behaves as a comparator, asserting itself when an ALERT
condition exists, de-asserting itself when the ALERT condition goes away.
