<> 129:0ab6a29f35bf 711 The function initializes the System Timer and its interrupt, and starts the System Tick Timer.
<> 129:0ab6a29f35bf 712 Counter is in free running mode to generate periodic interrupts.
<> 129:0ab6a29f35bf 713
<> 129:0ab6a29f35bf 714 \param [in] ticks Number of ticks between two interrupts.
<> 129:0ab6a29f35bf 715
<> 129:0ab6a29f35bf 716 \return 0 Function succeeded.
<> 129:0ab6a29f35bf 717 \return 1 Function failed.
