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.

Internal T
This limit register is an 8-bit read/write register that stores the twos
complement of the internal temperature upper limit, and 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.

Internal T
This limit register is an 8-bit read/write register that stores the
twos complement of the internal temperature lower limit, and
causes an interrupt and activates the INT/ INT output (if enabled).
For this to happen, the measured internal temperature value has
to be more negative than or equal to the value in this register.
Because it is an 8-bit register, the temperature resolution is 1°C.
The default value is −55°C.

External T
[Address = 0x27]
If Pin 7 and Pin 8 are configured for the external temperature
sensor, this limit register is an 8-bit read/write register that
stores the twos complement of the external temperature upper
limit, and causes an interrupt and activates the INT/ INT output
(if enabled). For this to happen, the measured external
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 −1°C.
If Pin 7 and Pin 8 are configured for AIN1 and AIN2 inputs,
this limit register is an 8-bit read/write register that stores the
AIN1 input upper limit, and causes an interrupt and activates
the INT/ INT output (if enabled). For this to happen, the
measured AIN1 value has to be greater than the value in this
register. Because it is an 8-bit register, the resolution is four
times less than the resolution of the 10-bit ADC. Because the
power-up default settings for Pin 7 and Pin 8 are AIN1 and
AIN2 inputs, the default value for this limit register is full-scale
voltage.

If Pin 7 and Pin 8 are configured for the external temperature
sensor, this limit register is an 8-bit read/write register that
stores the twos complement of the external temperature lower
limit, and causes an interrupt and activates the INT/ INT output
(if enabled). For this to happen, the measured external
temperature value has to be more negative than or equal to the
value in this register. Because it is an 8-bit register, the
temperature resolution is 1°C. The default value is 0°C.
If Pin 7 and Pin 8 are configured for AIN1 and AIN2 inputs,
this limit register is an 8-bit read/write register that stores the
AIN1 input lower limit, and causes an interrupt and activates
the INT/ INT output (if enabled). For this to happen, the
measured AIN1 value has to be less than or equal to the value in
this register. Because it is an 8-bit register, the resolution is four
times less than the resolution of the 10-bit ADC. Because the
power-up default settings for Pin 7 and Pin 8 are AIN1 and
AIN2 inputs, the default value for this limit register is 0 V.
