6.2.5 System Timer (SysTick)
The Cortex
® -M0 includes an integrated system timer, SysTick, which provides a simple, 24-bit
clear-on-write, decrementing, wrap-on-zero counter with a flexible control mechanism. The
counter can be used as a Real Time Operating System (RTOS) tick timer or as a simple counter.
When system timer is enabled, it will count down from the value in the SysTick Current Value
Register (SYST_CVR) to 0, and reload (wrap) to the value in the SysTick Reload Value Register
(SYST_RVR) on the next clock cycle, then decrement on subsequent clocks. When the counter
transitions to 0, the COUNTFLAG status bit is set. The COUNTFLAG bit clears on reads.
The SYST_CVR value is unknown on reset. Software should write to the register to clear it to 0
before enabling the feature. This ensures the timer will count from the SYST_RVR value rather
than an arbitrary value when it is enabled.
If the SYST_RVR is 0, the timer will be maintained with a current value of 0 after it is reloaded
with this value. This mechanism can be used to disable the feature independently from the timer
enable bit.

Cortex
® -M0 Technical Reference
Manual” and “ARM
® v6-M Architecture Reference Manual”.
