User manual
34.4.4.2.1 Calculating the RELOAD value
34.4.4.2 SysTick Reload Value Register
34.4.4.3 SysTick Current Value Register
34.4.4.4 SysTick Calibration Value Register
The LOAD register specifies the start value to load into the VAL register. See the register
summary in
Table 676. LOAD register bit assignments
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:
The VAL register contains the current value of the SysTick counter. See the register
summary in
Table 677. VAL register bit assignments
The CALIB register indicates the SysTick calibration properties. See the register summary
in
Table 678. CALIB register bit assignments

Table 674
To generate a multi-shot timer with a period 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.
To deliver a single SysTick interrupt after a delay of N processor clock cycles, use a
RELOAD of value N. For example, if a SysTick interrupt is required after 400 clock
pulses, set RELOAD to 400.
