12.7. One shot register

When the device is configured in standby mode and the BUSY bit is “0”, writing to the one shot register will

immediately initiate a new single temperature measurements for all channels. However, writing to the one shot

register while the device is in active mode will have no effect.

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.
