Description
0Alarm Speed
Read Only
This bit is set to “1” when fan is running at alarm speed. Once read, this bit
will not reassert on next monitoring cycle, even if the fan is still running at
alarm speed. This gives an indication as to when the fan is running full-speed,
such as in a
THERM condition.
1
Fan Fault
Read Only
This bit is set to “1” if fan becomes stuck or is running under speed. Once
read, this bit will reassert on next monitoring cycle, if the fan failure condi-
tion persists.
2Remote Temp High
Read Only
“1” indicates Remote high temperature limit has been exceeded. If the tem-
perature is still outside the Remote Temp High Limit, this bit will reassert on
next monitoring cycle.
3Remote Temp Low
Read Only
“1” indicates Remote low temperature limit exceeded (below). If the tempera-
ture is still outside the Remote Temp Low Limit, this bit will reassert on next
monitoring cycle.
4Remote Temp Therm
Read Only
“1” indicates Remote temperature Therm limit has been exceeded. This bit is
cleared on a read of Status Register 1. Once cleared, this bit will not get reas-
serted even if the
THERM condition persists.
5Remote Diode Error
Read Only
This bit is set to “1” if a short or open is detected on the remote temperature
channel. This test is only done on power-up, and if set to 1 cannot be cleared
by reading the Status Register 1.
6Loc Temp High
Read Only
“1” indicates Local Temp High Limit has been exceeded. If the temperature
is still outside the Local Temp High Limit, this bit will reassert on next
monitoring cycle.
7Loc Temp Low
Read Only
“1” indicates Local Temp Low Limit has been exceeded (below). If the tem-
perature is still outside the Local Temp Low Limit, this bit will reassert on
next monitoring cycle.

6Loc Therm
Read Only
“1” indicates Local temperature Therm limit has been exceeded. This bit clears on a read
of Status Register 2. Once cleared, this bit will not be reasserted even if the
THERM con-
dition persists.
7
THERM
Read Only
Set to “1” when
THERM is pulled low as an input. This bit clears on a read of Status
Register 2. The fan also runs full-speed.
