View source for TIM device tree configuration

==== TIM configured in PWM mode and trigger source ====
The example below shows how to configure '''TIM1 channel 1''' to act as:
* '''PWM output on PE9''', e.g. TIM1_CH1 ([[Pinctrl_device_tree_configuration|See pinctrl device tree configuration]] and [[GPIO internal peripheral]])
* '''trigger source''' (synchronous with PWM) for other internal peripheral such as [[ADC internal peripheral|STM32 ADC]]
