6.2.4 SysTick

The Cortex-M4 includes an integrated system timer, SysTick, which provides a simple, 24-bit, clear-on-write, decrementing, wrap-on-zero counter with a flexible control mechanism. The counter can be used in several different ways, and it is typically deployed either for operating system related purposes or as a general-purpose alarm mechanism.
