4. Mask the interrupt source by setting the
appropriate mask bit in the interrupt mask registers
(from Reg. 0x08 to Reg. 0x0A).
5. Take the appropriate action for a given interrupt
source.
6. Exit the interrupt handler.
7. Periodically poll the status register. If the interrupt
status bit clears, reset the corresponding interrupt
mask bit to 0. The SMBusALERT
 output and
status bits then behave as shown in Figure 31.

Interrupt Masking Register
Mask Registers 1, 2, and 3 are located at Addresses 0x08,
0x09, and 0x0A. These allow individual interrupt sources to
be masked out to prevent the SMBusALERT
  interrupts.
Masking   the   interrupt   source   prevents   only   the
SMBusALERT
 from being asserted; the appropriate status bit
is still set as normal.

FAN_FAULT
 Output
The FAN_FAULT
 output signals when one or both of the
fans stall. Pin 8, the FAN_FAULT
 output, is a dual-function
pin. It defaults to being a FAN_FAULT
 output but can be
reconfigured as an analog input reference for the THERM
input. To do this, set the FAN_FAULT
/REF (Bit 7) in
Configuration Register 4 (Address 0x04) to 1.
Fault Queue
The ADM1033 has a programmable fault queue option
that lets the user program the number of out-of-limit
measurements allowable before generating an ALERT
. The
fault queue affects only temperature measurement channels
and is only operational in SMBusALERT
 mode. It performs
some simple filtering, which is particularly useful at the
higher conversion rates (16, 32, and 64 conversions per
second), where averaging is not carried out.
There is a queue for each of the temperature channels. If
