                The STM32 ADC can be configured to use external trigger sources
                (e.g. timers, pwm or exti gpio). Then, it can be tuned to start
                conversions on external trigger by either:
+
                - "rising-edge"
                - "falling-edge"
                - "both-edges".
+
                Reading returns current trigger polarity.
+
                Writing value before enabling conversions sets trigger polarity.
