24 * \brief this code synchronizes the timers in order to optain synchronous PWMs
26 * \todo Test this function on various uC
27 * \todo modify if there exists other prescaler configurations
29 * \test This feature is not 100% shure for the moment, but has been tested on M32 and M128
32 * this code synchronizes the timers in order to optain synchronous PWMs,
33 * such a feature can be used for driving 3-phase motors with PWMS from different timers
36 * to synch PWMs you need to enshure that the timers have same prescales,
37 * and the same PWM mode
39 * There is one little side effect : if there are common prescalers in your controller they will all be reset
