Interrupt Status 1 Register (Read-Only) [Address 0x00]
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.

Table 11.
Bit Function
D0 1 when the internal temperature value exceeds THIGH limit.
Any internal temperature reading greater than the set limit
causes an out-of-limit event.
D1 1 when internal temperature value exceeds TLOW limit. Any
internal temperature reading less than or equal to the set
limit causes an out-of-limit event.
D2 This status bit is linked to the configuration of Pin 7 and
Pin 8. If configured for external temperature sensor, this bit
is 1 when the external temperature value exceeds THIGH
limit. The default value for this limit register is –1°C, so any
external temperature reading greater than the set limit
causes an out-of-limit event. If configured for AIN1 and
AIN2, this bit is 1 when AIN1 input voltage exceeds VHIGH or
VLOW limits.
D3 1 when external temperature value exceeds TLOW limit. The
default value for this limit register is 0°C, so any external
temperature reading less than or equal to the set limit
causes 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 VHIGH
limit. 1 when AIN2 voltage is less than or equal to its
corresponding VLOW limit.
D6 1 when AIN3 voltage is greater than its corresponding VHIGH
limit. 1 when AIN3 voltage is less than or equal to its
corresponding VLOW limit.
D7 1 when AIN4 voltage is greater than its corresponding VHIGH
limit. 1 when AIN4 voltage is less than or equal to its
corresponding VLOW limit.
Interrupt Status 2 Register (Read-Only) [Address = 0x01]
This 8-bit read-only register reflects the status of the VDD
interrupt 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.

Internal Temperature Value/V_DD Value Register LSBs
(Read-Only) [Address = 0x03]
This 8-bit read-only register stores the two LSBs of the 10-bit
temperature reading from the internal temperature sensor and
the two LSBs of the 10-bit supply voltage reading.
