Table 45. Register 0x0D—THERM Configuration Register1
Bit
Name
R/W
Description
0
Boost 1
R/W
Setting this bit to 0 causes the fans to go to maximum PWM on assertion of THERM1 as an
output. Setting this bit to 1 means that the fan speed is not affected when the THERM1
temperature limit is exceeded. Default = 0.
1
Boost 2
R/W
Setting this bit to 0 causes the fans to go to maximum PWM on assertion of THERM2 as an
output. Setting this bit to 1 means that the fan speed is not affected when the THERM2
temperature limit is exceeded. Default = 0.
[4:2]
THERM1 Timer Window
R/W
These bits set the timer window for measuring THERM1 assertions.
000 = 0.25 sec
001 = 0.5 sec
010 = 1 sec
011 = 2 sec
100 = 4 sec
101 = 8 sec
110 = 8 sec
111 = 8 sec
[7:5]
THERM2 Timer Window
R/W
These bits set the timer window for measuring THERM2 assertions.
000 = 0.25 sec
001 = 0.5 sec
010 = 1 sec
011 = 2 sec
100 = 4 sec
101 = 8 sec
110 = 8 sec
111 = 8 sec
1 POR = 0x00, Lock = Y, SW Reset = Y.
Table 46. Register 0x0E—THERM1 Configuration Register1
Bit
Name
R/W
Description
0
THERM1 Timer Enable
R/W
Enables the THERM1 timer circuit. Default = 0.
1
THERM1_Local
R/W
Setting the bit to 1 means that the THERM1 pin is asserted low as an output whenever
the local temperature exceeds the local THERM1 temperature limit. Default = 0.
2
THERM1_Remote 1
R/W
Setting the bit to 1 means that the THERM1 pin is asserted low as an output whenever
the Remote 1 temperature exceeds the Remote 1 THERM1 temperature limit. Default = 0.
3
THERM1_Remote 2
R/W
Setting the bit to 1 means that the THERM1 pin is asserted low as an output whenever
the Remote 2 temperature exceeds the Remote 2 THERM1 temperature limit. Default = 0.
4
THERM1_Remote 3
R/W
Setting the bit to 1 means that the THERM1 pin is asserted low as an output whenever
the Remote 3 temperature exceeds the Remote 3 THERM1 temperature limit. Default = 0.
[7:5]
Reserved
R
Reserved for future use.
1 POR = 0x00, Lock = Y, SW Reset = Y.
