3.5.16. Temperature Sensor
When temperature is measured, the receiver ADC is used to digitize the sensor response. Most receiver blocks are
disabled, and temperature measurement can only be triggered in Standby or Frequency Synthesizer modes.
The response of the temperature sensor is -1°C / Lsb. A CMOS temperature sensor is not accurate by nature, therefore it
should be calibrated at ambient temperature for precise temperature readings.
It takes less than 100 microseconds for the SX1231 to evaluate the temperature (from setting TempMeasStart to 1 to
TempMeasRunning reset).
3.5.17. Timeout Function
The SX1231 includes a Timeout function, which allows it to automatically shut-down the receiver after a receive sequence
and therefore save energy.
This timeout interrupt can be used to warn the companion processor to shut down the receiver and return to a lower power
mode.

ADVANCED COMMUNICATIONS & SENSING
Timeout interrupt is generated TimeoutRxStart x 8 x Tbit after switching to RX mode if RssiThreshold flag does not raise
within this time frame
Timeout interrupt is generated TimeoutRssiThresh x 8 x Tbit after RssiThreshold flag has been raised.
