ONE-SHOT REGISTER
The one-shot register initiates a conversion and comparison
cycle when the ADT7482 is in standby mode, after which the
device returns to standby. Writing to the one-shot register
address (0×0F) causes the ADT7482 to perform a conversion
and comparison on both the local and the remote temperature
channels. This is not a data register as such, and it is the write
operation to Address 0×0F that causes the one-shot conversion.
The data written to this address is irrelevant and is not stored.
CONSECUTIVE ALERT REGISTER
The value written to this register determines how many out-of-
limit measurements must occur before an ALERT is generated.
The default value is that one out-of-limit measurement generates
an ALERT. The maximum value that can be chosen is 4. This
register allows some filtering of the output. This is particularly
useful at the fastest three conversion rates, where no averaging
takes place. This register address is 0x22. For more information,
refer to Table 15.

1 Notes:
y = SMBus SCL timeout bit. Default = 0. See the Serial Bus Interface section
for more information.
z = SMBus SDA timeout bit. Default = 0. See the Serial Bus Interface section
for more information.
a = Mask Internal ALERTs.
x = Don’t care bit.
