+ * lines are alternative possibilities not used per default. But they can be changed
+ * manually instead of the suggested configuration. For example you can see that on
+ * PA_5 you can have a PWM using either Timer2/Channel1 or Timer8/Channel1N. Today I
+ * have decided to use Timer2/Channel1. But you can also notice that Timer2/Channel1
+ * is also used on PA_0. That means that today you cannot output two different PWM
+ * signals on PA_0 and PA_5 at the same time. If someone wants this, he will need to
+ * change the timer that is used on PA_5. This is why the other possibilities are
+ * commented to make this change easier without looking deeply into the mcu datasheet.
