5.3.3
The system clock has 5 clock sources which were generated from clock generator block. The
clock source switch depends on the register HCLK_S (CLKSEL0[2:0]). The block diagram is
showed in Figure 5-5.
The clock source of SysTick in Cortex-M0 core can use CPU clock or external clock
(SYST_CSR[2]). If using external clock, the SysTick clock (STCLK) has 5 clock sources. The
clock source switch depends on the setting of the register STCLK_S (CLKSEL0[5:3]. The block
diagram is showed in Figure 5-6.
