The LOAD register specifies the start value to load into the VAL register. See the register sum-
mary in
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 acti-
vated when counting from 1 to 0.
The RELOAD value is calculated according to its use:
• To generate a multi-shot timer with a period of N processor clock cycles, use a RELOAD
• To deliver a single SysTick interrupt after a delay of N processor clock cycles, use a RELOAD
value of N-1. For example, if the SysTick interrupt is required every 100 clock pulses, set
RELOAD to 99.
of value N. For example, if a SysTick interrupt is required after 400 clock pulses, set RELOAD
to 400.
