nrf52811: Temperature linearity compensation, manual or automatic?

Andy T

Does the nrf52811 temperature peripheral do automatic linearity compensation?
The product specification 1.0 says: "Linearity compensation can be implemented if required by the application", which indicates that it must be implemented in software, however I am confused about this errata [0] which reads as the compensation is automatically performed.

Is there any example on how to Do linear compensation if is must be implemented in software?

    Hi,

    The measured temperature is already linearized with a piecewise linearizations whose coefficients is listed in Table 2 in the link you provided. The linearization is automatic, and you don't need to implement anything in software. 

    The coefficients can be changed if you find new coefficients that provide a better result for chip you have (non-linearity varies from chip to chip).
