When Pin 6 is configured as THERM2
, only the high
temperature limits are relevant. If Flag 6 and/or Flag 4 are
set, the THERM2
output goes low to indicate the
temperature measurements are outside the programmed
limits. Flag 5 and Flag 3 have no effect on THERM2
. The
behavior of THERM2
is otherwise the same as THERM
.

2. These flags stay high until the status register is read or they are
reset by POR.
Offset Register
Offset errors may be introduced into the remote
temperature measurement by clock noise or by the thermal
diode being 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 Registers 0x11 (high byte) and 0x12 (low byte, left
justified). Only the upper 2 bits of Register 0x12 are used.
The MSB of Register 0x11 is the sign bit. The minimum
offset that can be programmed is 128癈, and the maximum
is +127.75癈. The value in the offset register is added to the
measured value of the remote temperature.
The offset register powers up with a default value of 0癈
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 ADT7461 is in standby mode,
after which the device returns to standby. Writing to the
one-shot register address (0x0F) causes the ADT7461 to
perform a conversion and comparison on both the internal
and the external temperature channels. This is not a data
register as such; the write operation to Address 0x0F 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. 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.
