27 TEMP Temperature sensor
The temperature sensor measures die temperature over the temperature range of the device. Linearity
compensation can be implemented if required by the application.
Listed here are the main features for TEMP:
Temperature range is greater than or equal to operating temperature of the device
Resolution is 0.25 degrees
TEMP is started by triggering the START task.
When the temperature measurement is completed, a DATARDY event will be generated and the result of the
measurement can be read from the TEMP register.
To achieve the measurement accuracy stated in the electrical specification, the crystal oscillator must be
selected as the HFCLK source, see CLOCK Clock control on page 101 for more information.
When the temperature measurement is completed, TEMP analog electronics power down to save power.
TEMP only supports one-shot operation, meaning that every TEMP measurement has to be explicitly started
using the START task.
