WebSep 5, 2024 · SysTick - system timer is a peripheral in CM3 kernel, embedded in NVIC. The system timer is a 24bit downward decreasing counter. The time of each count is 1/SYSCLK. Generally, we set the system clock SYSCLK equal to 72M. When the value of the reload value register decreases to 0, the system timer generates an interrupt to cycle back and forth.
