Table 21. Register 0×03 Status Register 2 Power-Up Default = 00H
Bit
Name
R/W
Description
0
Alarm 2 Speed
Read Only
This bit is set to “1” when Fan 2 is running at alarm speed. Once read, this bit is not reasserted on next
monitoring cycle, even if the fan is still running at alarm speed.
1
Fan 2 Fault
Read Only
This bit is set to “1” if Fan 2 becomes stuck or is running under speed.
2
Remote 2 High
Read Only
“1” indicates Remote 2 high temperature limit has been exceeded. If the temperature is still outside the
Remote 2 Temp High Limit, this bit reasserts on the next monitoring cycle.
3
Remote 2 Low
Read Only
“1” indicates Remote 2 low temperature limit exceeded (below). If the temperature is still outside the
Remote 2 Temp Low Limit, this bit reasserts on the next monitoring cycle.
4
Remote 2
Therm
Read Only
“1” indicates Remote 2 temperature Therm limit has been exceeded. This bit is cleared on reading
Status Register 2.
5
Remote Diode
2 Error
Read Only
This bit is set to “1” if a short or open is detected on the Remote 2 temperature channel. This test is only
done on power-up, and if set to 1 cannot be cleared by reading Status Register 2.
6
Local Therm
Read Only
“1” indicates local temperature therm limit has been exceeded. This bit clears on a read of Status
Register 2.
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.
Table 22. Register 0×06 Extended Temperature Resolution Power-On Default = 00H
Bit
Name
R/W
Description
<2:0>
Remote Temp 1
Read Only
Holds extended temperature resolution bits for Remote 1 channel.
<5:3>
Remote Temp 2
Read Only
Holds extended temperature resolution bits for Remote 2 channel.
<7:6>
Local Temp
Read Only
Holds extended temperature resolution bits for local temperature channel.
Table 23. Register 0×20 Fan Characteristics Register 1 Power-On Default = 5DH
Bit
Name
R/W
Description
<2:0>
Fan 1 Spin-Up
Read/Write
These bits contain the fan spin-up time to allow Fan 1 to overcome its own inertia.
000 = 200 ms
001 = 400 ms
010 = 600 ms
011 = 800 ms
100 = 1 sec
101 = 2 sec (Default)
110 = 4 sec
111 = 8 sec
<5:3>
PWM 1
Frequency
Read/Write
These bits allow programmability of the nominal PWM 1 output frequency driving Fan 1.
(Default = 31 Hz.)
000 = 11.7 Hz
001 = 15.6 Hz
010 = 23.4 Hz
011 = 31.25 Hz (Default)
100 = 37.5 Hz
101 = 46.9 Hz
110 = 62.5 Hz
111 = 93.5 Hz
