CYCCNT is an optional free-running 32-bit cycle counter. If the DWT unit implements CYCCNT then the DWT_CTRL.NOCYCCNT bit is RAZ, see Control register, DWT_CTRL. When implemented and enabled, CYCCNT increments on each cycle of the processor clock. When the counter overflows it wraps to …

WebJun 2, 2024 · This counter is incremented every CPU cycle (i.e. 168 million times per second). Whenever the CYCTAP bit in the cycle counter is toggled (0->1 or 1->0), we decrement a counter which started at the POSTPRESET value. When that counter hits 0, a PC sampling event is generated.

DWT->CYCCNT is part of the ARMv7m (CM3 and higher) "Data Watchpoint and Trace" unit of the CPU core, defined by ARM. It's an "optional" part of the ARM core, so not all chips have it. WebMay 21, 2015 · 3. Your code has two problems: You don't know whether the interrupt that increased SysTickMajor happened before or after you read the timer value into time. Operations on 64-bit values are not atomic on a 32-bit system. So the value for SysTickMajor could be updated by the interrupt between reading the two 32-bit words. gets the rainbow card
