The temperature-sensor control register controls the
internal and external temperature measurement.
IMUX<1:0>: Internal current-source MUX bits. Selects
the pin to be driven by the internal current sources as
shown in Table 20. The power-on default is 00.
This register is the internal temperature sensor calibra-
tion register.
TGAIN<7:0>: Factory-preset temperature gain correction
coefficient bits. This is the linear scaling factor used to
derive absolute temperature values from temperature val-
ues measured with the internal temperature sensor
(T
optimized for an internal voltage reference of 1.25V using
the four-current method. The power-on default varies.
