dkato 0:f782d9c66c49 711 The function initializes the System Timer and its interrupt, and starts the System Tick Timer.
dkato 0:f782d9c66c49 712 Counter is in free running mode to generate periodic interrupts.
dkato 0:f782d9c66c49 713
dkato 0:f782d9c66c49 714 \param [in] ticks Number of ticks between two interrupts.
dkato 0:f782d9c66c49 715
dkato 0:f782d9c66c49 716 \return 0 Function succeeded.
dkato 0:f782d9c66c49 717 \return 1 Function failed.
dkato 0:f782d9c66c49 718
dkato 0:f782d9c66c49 719 \note When the variable <b>__Vendor_SysTickConfig</b> is set to 1, then the
dkato 0:f782d9c66c49 720 function <b>SysTick_Config</b> is not included. In this case, the file <b><i>device</i>.h</b>
dkato 0:f782d9c66c49 721 must contain a vendor-specific implementation of this function.
