Hottest Temperature Status Register
High Limit Status Register
The Hottest Temperature Registers store the measured hottest temperature of all the selected external
diode channels (see
read 80h. The data format is the same as the temperature channels.
The Hottest Temperature Status Register flags which external diode temperature is hottest. If multiple
temperature channels measure the same temperature and are equal to the hottest temperature, then
hottest status will be based on the measurement order.
Bit 6 - EXT6 - The External Diode 6 channel is the hottest.
Bit 4 - EXT5 - The External Diode 5 channel is the hottest.
Bit 3 - EXT4 - The External Diode 4 channel is the hottest.
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
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.
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.
