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.

Interrupt Status 2 Register (Read-Only) [Address = 0x01]
This 8-bit read-only register reflects the status of the V
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
(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.

Function
1 when the internal temperature value exceeds T
Any internal temperature reading greater than the set limit
causes an out-of-limit event.
1 when internal temperature value exceeds T
internal temperature reading less than or equal to the set
limit causes an out-of-limit event.
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 T
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 V
V
1 when external temperature value exceeds T
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.
1 indicates a fault (open or short) for the external
temperature sensor.
