The SYST_RVR register specifies the start value to load into the SYST_CVR register.
• RELOAD
Value to load into the SYST_CVR register when the counter is enabled and when it reaches 0.
The RELOAD value can be any value in the range 0x00000001-0x00FFFFFF. A start value of 0 is possible, but has no
effect because the SysTick exception request and COUNTFLAG are activated when counting from 1 to 0.
The RELOAD value is calculated according to its use: For example, to generate a multi-shot timer with a period of N pro-
cessor clock cycles, use a RELOAD value of N-1. If the SysTick interrupt is required every 100 clock pulses, set RELOAD
to 99.
