When using timers in reload mode, the main intention is to generate circular interrupts with a
fixed reload time. But when interrupt service routines are called, a certain overhead will be
produced by the compiler (context save !). This note shows how to calculate the correct reload
value taking in account the produced extra code.


In this example, a
