High Limit Status Register 35h

The High Limit Status Register contains the status bits that are set when a temperature channel high

limit is exceeded. If any of these bits are set, the HIGH status bit in the Status Register is set. Reading

from the High Limit Status Register will clear all bits if. Reading from the register will also clear the

HIGH status bit in the Status Register.

The ALERT / THERM2 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 / THERM2 pin is configured as a

comparator output (see Section 5.5.2).

Bit 3 - E3HIGH - This bit is set when the External Diode 3 channel exceeds its programmed high limit.

Bit 2 - E2HIGH - This bit is set when the External Diode 2 channel exceeds its programmed high limit.

Bit 1 - E1HIGH - This bit is set when the External Diode 1 channel exceeds its programmed high limit.

Bit 0 - IHIGH - This bit is set when the Internal Diode channel exceeds its programmed high limit.

6.16

Low Limit Status Register 36h

The Low Limit Status Register contains the status bits that are set when a temperature channel drops

below the low limit. If any of these bits are set, then the LOW status bit in the Status Register is set.

Reading from the Low Limit Status Register will clear all bits. Reading from the register will also clear

the LOW status bit in the Status Register.

The ALERT / THERM2 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 / THERM2 pin is configured as a

comparator output (see Section 5.5.2).

Bit 3 - 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.
