AnnaBridge | 167:e84263d55307 | 847 | \brief System Tick Configuration |
AnnaBridge | 167:e84263d55307 | 848 | \details Initializes the System Timer and its interrupt, and starts the System Tick Timer. |
AnnaBridge | 167:e84263d55307 | 849 | Counter is in free running mode to generate periodic interrupts. |
AnnaBridge | 167:e84263d55307 | 850 | \param [in] ticks Number of ticks between two interrupts. |
AnnaBridge | 167:e84263d55307 | 851 | \return 0 Function succeeded. |
AnnaBridge | 167:e84263d55307 | 852 | \return 1 Function failed. |
AnnaBridge | 167:e84263d55307 | 853 | \note When the variable <b>__Vendor_SysTickConfig</b> is set to 1, then the |
AnnaBridge | 167:e84263d55307 | 854 | function <b>SysTick_Config</b> is not included. In this case, the file <b><i>device</i>.h</b> |
AnnaBridge | 167:e84263d55307 | 855 | must contain a vendor-specific implementation of this function. |
