This function configures time base source, NVIC and Low level hardware.

Note

This function is called at the beginning of program after reset and before the clock configuration. The Systick configuration is based on AHB clock and the NVIC configuration is set to Priority group 4. The time base configuration is done, time base tick starts incrementing.
