cleared when the appropriate High Limit, Low Limit, or THERM Limit register has been read or cleared.
Bit 7 - BUSY - This bit indicates that the ADC is currently converting. This bit does not cause either
the ALERT or THERM pins to be asserted.
Bit 4 - HIGH - This bit is set when any of the temperature channels exceeds its programmed high limit.
See the High Limit Status Register for specific channel information
will assert the ALERT pin.
Bit 3 - LOW - This bit is set when any of the temperature channels drops below its programmed low
limit. See the Low Limit Status Register for specific channel information
bit will assert the ALERT pin.
Bit 2 - FAULT - This bit is asserted when a diode fault is detected on any of the external diode
channels. See the External Diode Fault Register for specific channel information
set, this bit will assert the ALERT pin.
Bit 1 - THERM - This bit is set when the any of the temperature channels exceeds its programmed
THERM limit. See the THERM Limit Status Register for specific channel information
When set, this bit will assert the THERM pin.
The Configuration Register controls the basic operation of the device. This register is fully accessible
at either address.
Bit 7 - MASK_ALL - Masks the ALERT pin from asserting.
Bit 6 - RUN / STOP - Controls Active/Standby modes.
Bit 5 - ALERT/COMP - Controls the operation of the ALERT pin.

‘0’ (default) - The ALERT pin is not masked. If any of the appropriate status bits are set the ALERT
pin will be asserted.
‘1’ - The ALERT pin is masked. It will not be asserted for any interrupt condition unless it is
configured as a secondary THERM pin. The Status Registers will be updated normally.
‘0’ (default) - The device is in Active mode and converting on all channels.
‘1’ -The device is in Standby mode and not converting.
‘0’ (default) - The ALERT pin acts as described in
