The Interrupt Status Register 1 bits will be automatically set, by the aSC7611, whenever a fault condition is detected. A fault
condition is detected whenever a measured value is outside the window set by its limit registers. ZN1 bit will be set when a
diode fault condition, such as an open or short, is detected. More than one fault may be indicated in the interrupt register
when read. The register will hold a set bit(s) until the event is read by software. The contents of this register will be cleared
(set to 0) automatically by the aSC7611 after it is read by software, if the fault condition no longer exists. Once set, the
Interrupt Status Register 1 bits will remain set until a read event occurs, even if the fault condition no longer exists. This
register is read-only – a write to this register has no effect.

The aSC7611 automatically sets this bit to 1 when the 2.5V input voltage is
less than or equal to the limit set in the 2.5V Low Limit register or greater than
the limit set in the 2.5V High Limit register.

The aSC7611 automatically sets this bit to 1 when the VCCP input voltage is
less than or equal to the limit set in the VCCP Low Limit register or greater
than the limit set in the VCCP High Limit register.

3.3V Limits
Exceeded
R
0
The aSC7611 automatically sets this bit to 1 when the 3.3V input voltage is
less than or equal to the limit set in the 3.3V Low Limit register or greater than
the limit set in the 3.3V High Limit register.
3
5V Limits
Exceeded
R
0
The aSC7611 automatically sets this bit to 1 when the 5V input voltage is less
than or equal to the limit set in the 5V Low Limit register or greater than the
limit set in the 5V High Limit register.
4
Zone 1 Limit
Exceeded
R
0
The aSC7611 automatically sets this bit to 1 when the temperature input
measured by the Remote1- and Remote1+ inputs is less than or equal to the
limit set in the Processor (Zone 1) Low Temp register or more than the limit set
in the Processor (Zone 1) High Temp register. This bit will be set when a
diode fault is detected.
5
Zone 2 Limit
Exceeded
R
0
The aSC7611 automatically sets this bit to 1 when the temperature input
measured by the internal temperature sensor is less than or equal to the limit
set in the thermal (Zone 2) Low Temp register or greater than the limit set in
the Internal (Zone 2) High Temp register.
6
Zone 3 Limit
Exceeded
R
0
The aSC7611 automatically sets this bit to 1 when the temperature input
measured by the second remote temperature sensor is less than or equal to
the limit set in the thermal (Zone 3) Low Temp register or greater than the limit
set in the Internal (Zone 3) High Temp register.

Register 2
R
0
If there is a set bit in Status Register 2, this bit will be set to 1.
