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, then 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 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 - 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.
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.
