Hottest Temperature Registers
The Hottest Temperature Registers store the measured hottest temperature of all the selected external
diode channels (see Section 5.22). If no External diodes are selected then the High Byte Register will
read 80h. The data format is the same as the temperature channels.
5.17
Hottest Temperature Status Register
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 7 - EXT7 - The External Diode 7 channel is the hottest.
Bit 6 - EXT6 - The External Diode 6 channel is the hottest.
Bit 4 - EXT5 - The External Diode 5 channel is the hottest.
