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.

written to this register, which is then added to the measured
result before it is stored or compared to limits. In this way, a

V
This limit register is an 8-bit read/write register that stores the
V
INT/ INT output (if enabled). For this to happen, the measured
V
default value is 5.46 V.

V
This limit register is an 8-bit read/write register that stores the
V
INT output (if enabled). For this to happen, the measured V
value has to be less than or equal to the value in this register.
The default value is 2.7 V.

Internal T
This limit register is an 8-bit read/write register that stores the
twos complement of the internal temperature upper limit that
causes an interrupt and activates the INT/ INT output (if enabled).
For this to happen, the measured internal temperature value has
to be greater than the value in this register. Because it is an 8-bit
register, the temperature resolution is 1°C. The default value
is 100°C.
