Figure 52. Phase 2 of 10-Bit Read
If an MSB register is read first, its corresponding LSB register is
not locked, leaving the user with the option of just reading back
8 bits (MSB) of a 10-bit conversion result. Reading an MSB
register first does not lock other MSB registers, and likewise
reading an LSB register first does not lock other LSB registers.

Interrupt Status 1 Register (Read-Only) [Address = 00h]
This 8-bit read-only register reflects the status of some of the
interrupts that can cause the INT/INT pin to go active. This
register is reset by a read operation, provided that any out-of-
limit event has been corrected. It is also reset by a software reset.

Bit
Function
D0
1 when the internal temperature value exceeds T
HIGH
limit. Any
internal temperature reading greater than the set limit will
cause an out-of-limit event.
D1
1 when internal temperature value exceeds T
LOW
limit. Any
internal temperature reading less than or equal to the set limit
will cause an out-of-limit event.
D2
This status bit is linked to the configuration of Pins 7 and 8. If
configured for the external temperature sensor, this bit is 1
when the external temperature value the exceeds T
HIGH
limit.
The default value for this limit register is –1°C, so any external
temperature reading greater than the set limit will cause an
out-of-limit event. If configured for AIN1 and AIN2, this bit is 1
when AIN1 input voltage exceeds V
HIGH
or V
LOW
limits.
D3
1 when external temperature value exceeds T
LOW
limit. The
default value for this limit register is 0°C, so any external
temperature reading less than or equal to the set limit will
cause an out-of-limit event.
D4
1 Indicates a fault (open or short) for the external temperature
sensor.
D5
1 when AIN2 voltage is greater than its corresponding V
HIGH
limit. 1 when AIN2 voltage is less than or equal to its
corresponding V
LOW
limit.
D6
1 when AIN3 voltage is greater than its corresponding V
HIGH
limit. 1 when AIN3 voltage is less than or equal to its
corresponding V
LOW
limit.
D7
1 when AIN4 voltage is greater than its corresponding V
HIGH
limit. 1 when AIN4 voltage is less than or equal to its
corresponding V
LOW
limit.
Interrupt Status 2 Register (Read-Only) [Address = 01h]
This 8-bit read-only register reflects the status of the V
DD
inter-
rupt that can cause the INT/INT pin to go active. This register is
reset by a read operation, provided that any out-of-limit event
has been corrected. It is also reset by a software reset.
