• NOREF
Reads as zero.
• SKEW
Reads as zero
• TENMS
Read as 0x000030D4. The SysTick calibration value is fixed at 0x000030D4 (12500), which allows the generation of a time
base of 1 ms with SysTick clock at 5 MHz (100/8 = 12.5 MHz)

The CALIB register indicates the SysTick calibration properties. See the register summary in
Table 12-33 on page 153
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.
