Read as 0x0002904. The SysTick calibration value is fixed at 0x0002904 (10500), which allows the generation of a time

base of 1 ms with SysTick clock at 10.5 MHz (84/8 = 10.5 MHz)

SysTick Calibration Value Register

SysTick design hints and tips

The CALIB register indicates the SysTick calibration properties. See the register summary in

Table 13-33 on page 207

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

mode, the SysTick counter stops.

Ensure software uses aligned word accesses to access the SysTick registers.
