The ALERT pin will be set if the programmed number of consecutive alert counts have been met and
any of these status bits are set.
The status bits will remain set until read unless the ALERT pin is configured as a comparator output
(see
Bit 3 - E3LOW - This bit is set when the External Diode 3 channel drops below its programmed low
limit.
Bit 2 - E2LOW - This bit is set when the External Diode 2 channel drops below its programmed low
limit.
Bit 1 - E1LOW - This bit is set when the External Diode 1 channel drops below its programmed low
limit.
Bit 0 - ILOW - This bit is set when the Internal Diode channel drops below its programmed low limit.
The THERM Limit Status Register contains the status bits that are set when a temperature channel
THERM Limit is exceeded. If any of these bits are set, then the THERM status bit in the Status Register
is set. Reading from the THERM Limit Status Register will not clear the status bits. Once the
temperature drops below the THERM Limit minus the THERM Hysteresis, the corresponding status
bits will be automatically cleared. The THERM bit in the Status Register will be cleared when all
individual channel THERM bits are cleared.
Bit 3 - E3THERM - This bit is set when the External Diode 3 channel exceeds it’s programmed THERM
Limit. When set, this bit will assert the THERM pin.
Bit 2 - E2THERM - This bit is set when the External Diode 2 channel exceeds it’s programmed THERM
Limit. When set, this bit will assert the THERM pin.
Bit 1 - E1THERM - This bit is set when the External Diode 1 channel exceeds it’s programmed THERM
limit. When set, this bit will assert the THERM pin.
Bit 0- ITHERM - This bit is set when the Internal Diode channel exceeds it’s programmed THERM limit.
When set, this bit will assert the THERM pin.

The Filter Configuration Register controls the digital filter on the External Diode 1 channel.
Bits 1-0 - FILTER[1:0] - Control the level of digital filtering that is applied to the External Diode
temperature measurements. See
