Table XVI. Register 0x02 Status Register 1 Power-On Default = 00H

Bit

Name

Description

Alarm 1 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.

Fan 1 Fault

Read Only

This bit is set to “1” if Fan 1 becomes stuck or is running under speed.

Remote 1 High

Read Only

“1” indicates Remote 1 high temperature limit has been exceeded. If the

temperature is still outside the Remote 1 Temp High Limit, this bit will reas-

sert on next monitoring cycle.

Remote 1 Low

Read Only

“1” indicates Remote 1 low temperature limit exceeded (below). If the tem-

perature is still outside the Remote 1 Temp Low Limit, this bit will reassert

on next monitoring cycle.

Remote 1 Therm

Read Only

“1” indicates Remote 1 temperature Therm limit has been exceeded. This bit

is cleared on a read of Status Register 1.

Remote Diode 1 Error

Read Only

This bit is set to “1” if a short or open is detected on the Remote 1 tempera-

ture channel. This test is only done on power-up, and if set to 1 cannot be

cleared by reading the Status Register 1.

Local 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.

Local 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.

Table XVII. Register 0x03 Status Register 2 Power-Up Default = 00H

Bit

Name

Description

Alarm 2 Speed

Read Only

This bit is set to “1” when Fan 2 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.

Fan 2 Fault

Read Only

This bit is set to “1” if Fan 2 becomes stuck or is running under speed.

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 will reas-

sert on the next monitoring cycle.

Remote 2 Low

Read Only

“1” indicates Remote 2 low temperature limit exceeded (below). If the tem-

perature is still outside the Remote 2 Temp Low Limit, this bit will reassert

on the next monitoring cycle.

Remote 2 Therm

Read Only

“1” indicates Remote 2 temperature Therm limit has been exceeded. This bit

is cleared on reading Status Register 2.

Remote Diode 2 Error

Read Only

This bit is set to “1” if a short or open is detected on the Remote 2 tempera-

ture channel. This test is only done on power-up, and if set to 1 cannot be

cleared by reading Status Register 2.

Local Therm

Read Only

“1” indicates Local temperature Therm limit has been exceeded. This bit

clears on a read of Status Register 2.

THERM

Read Only

Set to “1” when THERM is pulled low as an input. This bit clears on a read

of Status Register 2.
