Bit 3 - EXT3 - The External Diode 3 channel is the hottest.
Bit 2 - EXT2 - The External Diode 2 channel is the hottest.
Bit 1 - EXT1 - The External Diode 1 channel is the hottest.
Bit 0 - INT - The Internal Diode channel is the hottest.
The High Limit Status Register contains the status bits that are set when a temperature channel high
limit is exceeded for a number of consecutive readings as set by the consecutive alert counts (see
Section
Reading from the High Limit Status Register will clear all bits if the error condition has been removed.
Reading from the register will also clear the HIGH status bit in the Status Register.
The ALERT pin will be set if any of these status bits are set.
Bit 7 - E7HIGH - This bit is set when the External Diode 7 channel meets or exceeds its programmed
high limit.
Bit 6 - E6HIGH - This bit is set when the External Diode 6 channel meets or exceeds its programmed
high limit.
Bit 5 - E5HIGH - This bit is set when the External Diode 5 channel meets or exceeds its programmed
high limit.
Bit 4 - E4HIGH - This bit is set when the External Diode 4 channel meets or exceeds its programmed
high limit.
Bit 3 - E3HIGH - This bit is set when the External Diode 3 channel meets or exceeds its programmed
high limit.
Bit 2 - E2HIGH - This bit is set when the External Diode 2 channel meets or exceeds its programmed
high limit.
Bit 1 - E1HIGH - This bit is set when the External Diode 1 channel meets or exceeds its programmed
high limit.
Bit 0 - IHIGH - This bit is set when the Internal Diode channel meets or exceeds its programmed high
limit.
