1. These flags stay high until the status register is read or they
are reset by POR unless Pin 6 is configured as THERM2.
Then, only Bit 2 remains high until the status register is read
or is reset by POR.
Offset Register
Offset errors can be introduced into the remote
temperature measurement by clock noise or when the
thermal diode is located away from the hot spot. To achieve
the specified accuracy on this channel, these offsets must be
removed.
The offset value is stored as a 10−bit, twos complement
value in Register 0x11 (high byte) and Register 0x12 (low
byte, left justified). Only the upper two bits of Register 0x12
are used. The MSB of Register 0x11 is the sign bit. The
minimum, programmable offset is −128
°C, and the
maximum is +127.75
°C. The value in the offset register is
added to, or subtracted from, the measured value of the
remote temperature.
The offset register powers up with a default value of 0
°C
and has no effect unless the user writes a different value to it.

One−Shot Register
The one−shot register is used to initiate a conversion and
comparison cycle when the ADT7461A is in standby mode,
after which the device returns to standby. Writing to the
one−shot register address (0x0F) causes the ADT7461A to
perform a conversion and comparison on both the internal
and the external temperature channels. This is not a data
register as such, and it is the write operation to Address 0x0F
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−limitmeasurements 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. The purpose of this register is to
allow the user to perform some filtering of the output. This
is particularly useful at the fastest three conversion rates,
where no averaging takes place. This register is at Address
0x22.

NOTE: x = don’t care bits, and y = SMBus timeout bit.
Default = 0. See SMBus section for more information.
