◆ SystemCoreClock

uint32_t SystemCoreClock

Holds the SYSCLK system core clock, which is the system clock frequency supplied to the SysTick timer and the processor core clock.

This variable implements CMSIS Core global variable. Refer to the CMSIS documentation for more details. This variable can be used by debuggers to query the frequency of the debug timer or to configure the trace clock speed.

Attention
Compilers must be configured to avoid removing this variable in case the application program is not using it. Debugging systems require the variable to be physically present in memory so that it can be examined to configure the debugger.
