SHUTDOWN
The ADT7410 can be placed in shutdown mode by writing 1
to Bit 5 and 1 to Bit 6 of the configuration register (Register
Address 0x03), in which case the entire IC is shut down and
no further conversions are initiated until the ADT7410 is
taken out of shutdown mode. The ADT7410 can be taken
out of shutdown mode by writing 0 to Bit 5 and 0 to Bit 6 in
the configuration register (Register Address 0x03). The
ADT7410 typically takes 1 ms (with a 0.1 μF decoupling
capacitor) to come out of shutdown mode. The conversion
result from the last conversion prior to shutdown can still be
read from the ADT7410 even when it is in shutdown mode.
When the part is taken out of shutdown mode, the internal
clock is started and a conversion is initiated.

FAULT QUEUE
Bit 0 and Bit 1 of the configuration register (Register Address
0x03) are used to set up a fault queue. The queue can facilitate up
to four fault events to prevent false tripping of the INT and CT pins
when the ADT7410 is used in a noisy temperature environment.
The number of faults set in the queue must occur consecutively
to set the INT and CT outputs. For example, if the number of
faults set in the queue is four, then four consecutive temperature
conversions must occur with each result exceeding a temperature
limit in any of the limit registers before the INT and CT pins are
activated. If two consecutive temperature conversions exceed a
temperature limit and the third conversion does not, the fault
count is reset back to zero.
