Interrupt Mask 2 Register (Read/Write) [Address = 1Eh]
This mask register is an 8-bit read/write register that can be
used to mask out any interrupts that can cause the INT/INT pin
to go active.

Internal Temperature Offset Register (Read/Write)
[Address = 1Fh]
This register contains the offset value for the internal
temperature channel. A twos complement number can be
written to this register, which is then added to the measured
result before it is stored or compared to limits. In this way, a sort
of one-point calibration can be done whereby the whole
transfer function of the channel can be moved up or down.
From a software point of view this may be a very simple method
to vary the characteristics of the measurement channel if the
thermal characteristics change. Because it is an 8-bit register, the
temperature resolution is 1°C.

External Temperature Offset Register (Read/Write)
[Address = 20h]
This register contains the offset value for the external tempera-
ture channel. A twos complement number can be written to this
register, which is then added to the measured result before it is
stored or compared to limits. In this way, a sort of one-point
calibration can be done whereby the whole transfer function of
the channel can be moved up or down. From a software point of
view, this may be a very simple method to vary the character-
istics of the measurement channel if the thermal characteristics
change. Because it is an 8-bit register, the temperature resolution
is 1°C.

Limit Register (Read/Write) [Address = 23h]
This limit register is an 8-bit read/write register that stores the
V
DD
upper limit that will cause an interrupt and activate the
INT/INT output (if enabled). For this to happen, the measured
V
DD
value has to be greater than the value in this register. The
default value is 5.46 V.
