T2 = Pin 2 external temperature sensor (Remote)
Fintek test mode used only
This bit is unused and always set to 1
Set to 1, T1 temperature exceeds high limit will not generate an ALERT.
Set to 0, T1 temperature exceeds high limit will generate an ALERT.
Set to 1, T1 temperature goes below low limit will not generate an ALERT.
Set to 0, T1 temperature goes below low limit will generate an ALERT.
Set to 1, T2 temperature exceeds high limit will not generate an ALERT.
Set to 0, T2 temperature exceeds high limit will generate an ALERT.
Set to 1, T2 temperature goes below low limit will not generate an ALERT.
Set to 0, T2 temperature goes below low limit will generate an ALERT.
This bit is unused and always set to 1
Set to 1, T2 temperature exceeds its thermal limit will not generate an ALERT.
Set to 0, T2 temperature exceeds its thermal limit will generate an ALERT.
Set to 1, FAN count exceeds its limit will not generate an ALERT.
Set to 0, FAN count exceeds its limit will generate an ALERT.
Set to 1, T1 temperature exceeds its thermal limit will not generate an ALERT.
Set to 0, T1 temperature exceeds its thermal limit will generate an ALERT.
Fintek test mode used only
Select method of controlling PWM duty and frequency to FINTEK mode.
This bit is unused and always set to 0
When bit7 set to 0, tachometer input filter can be selected here.
