The STM32F4xx TIM1 peripheral offers the possibility to program in advance the
configuration for the next TIM1 outputs behaviour (step) and change the configuration
of all the channels at the same time. This operation is possible when the COM
(commutation) event is used.
The COM event can be generated by software by setting the COM bit in the TIM1_EGR
register or by hardware (on TRC rising edge).
In this example, a software COM event is generated each 1 ms: using the SysTick
interrupt.
The TIM1 is configured in Timing Mode, each time a COM event occurs, a new TIM1
configuration will be set in advance.
