Hello,

The SysTick counter runs on the processor clock. If this clock signal is stopped for low power mode, the SysTick counter stops. 

Please refer to SysTick timer (STK) section in your related product Programming manual (

http://www.st.com/content/ccc/resource/technical/document/programming_manual/6c/3a/cb/e7/e4/ea/44/9b/DM00046982.pdf/files/DM00046982.pdf/jcr:content/translations/en.DM00046982.pdf

) for more clarification.

If you are Cube user you can use

the systick example from the firmware library 

that show how to use the default configuration of SysTick:

STM32Cube_FW_F3_V1.7.0\Projects\STM32F3-Discovery\Examples\Cortex\CORTEXM_SysTick

Best Regards

As a first thing, don't turn it on.

You can also

SysTick->CTRL  = 0;
