WebMar 7, 2024 · Clock-gated systick is useless. I'm sure thats not how its supposed to work. It seems more likely that I've overlooked something. If the RM diagram is correct, the clock gating happens upstream of the systick clock, which can't be right. I have checked the errata. The only implementation-defined behavior in ARMs SysTick is the clock source. http://www.iotword.com/10076.html
