WebMay 6, 2024 · The systick is essentially a 24-bit timer counter running at 48MHz that ticks down to zero. At the beginning of each cycle the systick timer is loaded with the value 47999. At 48MHz it takes exactly 1ms for the timer to reach zero (underflow), whereupon it’s reloaded and continues to count down oncemore. WebSysTick Control and Status Register. The SysTick SYST_CSR register enables the SysTick features. The register resets to 0x00000000, or to 0x00000004 if your device does not …
