Interrupt Status 2 Register (Read-Only) [Address = 01h]
This 8-bit read-only register reflects the status of the V
AIN5 to AIN8 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 is corrected. It is also reset by a software reset.

Function
1 when 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
Any 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 external temperature value exceeds T
The default value for this limit register is –1°C, so any external
temperature reading greater than the limit set causes an
out-of-limit event. If configured for AIN1 and AIN2, this bit is
1 when the AIN1 input voltage exceeds V
1 when external temperature value exceeds T
The default value for this limit register is 0°C, so any
external temperature reading less than or equal to the
limit set causes an out-of-limit event.
1 indicates a fault (open or short) for the external temp sensor.

Internal Temperature Value/V
(Read-Only) [Address = 03h]
This internal temperature value and V
8-bit read-only register. It stores the two LSBs of the 10-bit
temperature reading from the internal temperature sensor and
also the two LSBs of the 10-bit supply voltage reading.

External Temperature Value and AIN1 to AIN4 Register
LSBs (Read-Only) [Address = 04h]
This is an 8-bit read-only register. Bit D2 to Bit D7 store the two
LSBs of the analog inputs AIN2 to AIN4. Bit D0 and Bit D1 are
used to store the two LSBs of either the external temperature
value or AIN1 input value. The type of input for D0 and D1 is
selected by Bit 1 and Bit 2 of the Control Configuration 1 register.
