T2 = Pin 2 external temperature sensor (Remote)
T2 = Pin 2 external temperature sensor (Remote)
Set to 0, the F75363’s PWM output continues to output the control signal while in
standby. (when bit 6 is set to 1)
These bits are unused and always set to 0
Set to 1, pin6 is fan Tachometer input.
Set to 0, pin6 is ALERT output.
This bit is unused and always set to 0
Set to 1, an ALERT will be generated if consecutive abnormal events occur three times.
Set to 0, an ALERT will be generated if any abnormal event occurs.
Set to 1, ADC is converting.
Set to 1, T1 temperature exceeds high limit.
Set to 0, T1 temperature does not exceed high limit.
Set to 1, T1 temperature goes below low limit.
Set to 0, T1 temperature does not goes below low limit.
Set to 1, T2 temperature exceeds high limit.
Set to 0, T2 temperature does not exceed high limit.
Set to 1, T2 temperature goes below low limit.
Set to 0, T2 temperature does not goes below low limit.
Set to 1, T2 is open-circuit or shorted to VDD.
Set to 0, T2 is not open-circuit and not shorted to VDD.
Set to 1, T2 temperature exceeds its thermal limit.
Set to 0, T2 temperature does not exceed its thermal limit.
Set to 1, FAN count is higher than the FAN limit value
Set to 0, FAN count is equal or lower than the FAN limit value.
