Writing to this register initiates a single conversion cycle.

Data is not stored and always reads 00h

00h

Note: W = Write.

12.8. Therm Limit registers

The Therm Limit registers are used to set temperatures for thermal event. Once the measured temperature of

any channel exceeds the corresponding Therm Limit, the

______

THERM /ADDR pin is asserted. Note that the limit

setting data format must match the chosen data format of the temperature reading registers.

The

______

THERM /ADDR pin cannot be masked by either MASK_ALL bit or individual mask bit. Additionally, the

______

THERM /ADDR pin will be deasserted once the measured temperature drops below the corresponding Therm

Limit minus the Therm Hysteresis.
