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 - SW_SYS - This bit is set when any of the external diode channels meet or exceed the respected
THERM Limits. See the Therm Status Register for specific channel information
Bit 0 - HWSD - This bit is set when the External Diode 1 Temperature meets or exceeds the Hardware
Critical / Thermal Shutdown Limit. When set, this bit will assert the SYS_SHDN pin. This bit is cleared
when read if the SYS_SHDN pin has been released.
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 5 - ALERT/COMP - Controls the operation of the ALERT pin.
Bit 1 - DAVG_DIS - Disables the dynamic averaging feature on all temperature channels (see

‘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. The Status
Registers will be updated normally.
‘0’ (default) - The ALERT pin acts as described in
‘1’ - The ALERT pin acts in comparator mode as described in
MASK_ALL bit is ignored.
‘0’ (default) - The dynamic averaging feature is enabled. All temperature channels will be converted
with an averaging factor that is based on the conversion rate as shown in
‘1’ - The dynamic averaging feature is disabled. All temperature channels will be converted with a
maximum averaging factor of 1x (equivalent to 11-bit conversion). For higher conversion rates (i.e.
more conversions per second), this averaging factor will be reduced as shown in
4.5.6).
