Table 45. Register 0x0D THERM Configuration Register1

Bit

Name

R/W

Description

Boost 1

R/W

Setting this bit to 0 causes the fans to go to full speed 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.

Boost 2

R/W

Setting this bit to 0 causes the fans to go to full speed 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

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

Enable THERM1 Timer

R/W

Enables the THERM1 timer circuit. Default = 0.

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.

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.

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.

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

Reserved for future use.

1 POR = 0x00, Lock = Y, SW Reset = Y.
