Analog-to-digital converter (ADC)

Conversions without DMA and without overrun detection

It may be useful to let the ADC convert one or more channels without reading the data each
time (if there is an analog watchdog for instance). For that, the DMA must be disabled
(DMA = 0) and the EOC bit must be set at the end of a sequence only (EOCS = 0). In this
configuration, overrun detection is disabled.

Temperature sensor

The temperature sensor can be used to measure the ambient temperature (T
device.
Figure 66
When not in use, the sensor can be put in power down mode.
Note: The TSVREFE bit must be set to enable the conversion of both internal channels: the
ADC1_IN18 (temperature sensor) and the ADC1_IN17 (VREFINT).
