^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  5) 		The STM32 ADC can be configured to use external trigger sources
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  6) 		(e.g. timers, pwm or exti gpio). Then, it can be tuned to start
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  7) 		conversions on external trigger by either:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  8) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  9) 		- "rising-edge"
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 10) 		- "falling-edge"
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 11) 		- "both-edges".
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 12) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 13) 		Reading returns current trigger polarity.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 14) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 15) 		Writing value before enabling conversions sets trigger polarity.
