An on-chip wide-temperature range temperature sensor is integrated. It provides
temperature sensing capability of −40 °C ~ 85 °C. ADC0 is dedicated for the temperature
sensor, and the temperature sensor is measured through Anin03. To get an accurate
temperature value, it is necessary to get supply voltage by measuring the internal
reference voltage V
manual for detailed usage of temperature sensor.
A single input channel can be selected for conversion. A single conversion will be
performed and the result placed in the result register which corresponds to the selected
input channel. An interrupt, if enabled, will be generated after the conversion completes.
A single input channel can be selected for continuous conversion. The results of the
conversions will be sequentially placed in the four result register. The user may select
whether an interrupt can be generated after every four conversions. Additional conversion
results will again cycle through the four result register, overwriting the previous results.
Continuous conversions continue until terminated by the user.
