Description
0
Alarm 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 condition persists.
2
Remote Temp High
Read Only
1 indicates Remote high temperature limit has been exceeded. If the temperature
is still outside the Remote Temp High Limit, this bit will reassert on next monitoring
cycle.
3
Remote Temp Low
Read Only
1 indicates Remote low temperature limit exceeded (below). If the temperature is
still outside the Remote Temp Low Limit, this bit will reassert on next monitoring
cycle.
4
Remote 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 reasserted even if
the THERM
condition persists.
5
Remote 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.
6
Loc 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.
7
Loc Temp Low
Read Only
1 indicates Local Temp Low Limit has been exceeded (below). If the temperature is
still outside the Local Temp Low Limit, this bit will reassert on next monitoring cycle.

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
condition 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.
