Description
OVT = 1 indicates that one of the THERM overtemperature limits has been exceeded. This bit
is cleared on a read of the status register when the temperature drops below THERM – T HYST .
FAN1 = 1 indicates that Fan 1 has dropped below minimum speed or has stalled. This bit is not
set when the PWM1 output is off.
FAN2 = 1 indicates that Fan 2 has dropped below minimum speed or has stalled. This bit is not
set when the PWM2 output is off.
FAN3 = 1 indicates that Fan 3 has dropped below minimum speed or has stalled. This bit is not
set when the PWM3 output is off.
F4P = 1 indicates that Fan 4 has dropped below minimum speed or has stalled. This bit is not
set when the PWM3 output is off.
When Pin 9 is programmed as a GPIO output, writing to this bit determines the logic output of
the GPIO.
If Pin 9 is configured as the THERM timer input for THERM monitoring, this bit is set when the
THERM assertion time exceeds the limit programmed in the THERM timer limit register (0x7A).
D1 = 1 indicates either an open or short circuit on the Thermal Diode 1 inputs.
D2 = 1 indicates either an open or short circuit on the Thermal Diode 2 inputs.

1. Setting the Configuration Register 1 Lock bit has no effect on these registers.
2. 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).

1. Exceeding any of these temperature limits by 1 ° C causes 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.
2. 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).
