Event timer

The SysTick timer is an ARM® standard system timer in the NVIC. The SysTick timer can

be clocked from either the FCLK (the clock going into the CPU) or the Sleep Timer clock.

FCLK is either the SCLK or PCLK as selected by CLK_CPUCR (see Section 6.3.5: Clock

switching on page 51).

6.4.5
