Description
Reserved for future use
A one indicates that one of the
THERM
overtemperature limits has been exceeded.
This bit gets cleared on a read of the Status Register when the temperature drops below
THERM
– T
HYST
.
A one indicates that Fan 1 has dropped below minimum speed or has stalled.
This bit does NOT get set when the PWM 1 output is off.
A one indicates that Fan 2 has dropped below minimum speed or has stalled.
This bit does NOT get set when the PWM 2 output is off.
A one indicates that Fan 3 has dropped below minimum speed or has stalled.
This bit does NOT get set when the PWM 3 output is off.
A one indicates that Fan 4 has dropped below minimum speed or has stalled.
This bit does NOT get set when the PWM 3 output is off.
If Pin 9 is configured as the
THERM
timer input for
THERM
monitoring, then this bit
gets set when the
THERM
assertion time exceeds the limit programmed in the
THERM
Limit Register (Reg. 0x7A).
A one indicates either an open or short circuit on the Thermal Diode 1 inputs.
A one indicates either an open or short circuit on the Thermal Diode 2 inputs.

Setting the Configuration Register 1 Lock bit has no effect on these registers.
High Limits: An interrupt is generated when a value exceeds its high limit (> comparison).
Low Limits: An interrupt is generated when a value is equal to or below its low limit (
≤
comparison).

Exceeding any of these temperature limits by 1 C will cause the appropriate status bit to be set in the Interrupt Status Register. Setting the Configuration Register 1 Lock
bit has no effect on these registers.
High Limits: An interrupt is generated when a value exceeds its high limit (> comparison).
Low Limits: An interrupt is generated when a value is equal to or below its low limit (
≤
comparison).
